Best Turbo 400 Rebuild Kit: 10 Kits Compared

#1 · Best Overall

1. Raybestos Stage 1 Level 2

• Weight: 13 lb

Best for: Expanded Raybestos service parts.

Why it ranks #1: Raybestos Stage 1 frictions and Kolene steels come with front and reverse bands, filter, bushings, washer and bearing kits, plus seals and gaskets.

A washer kit and bearing kit distinguish this Chevy-compatible Raybestos Stage 1 TH400 package from a more basic rebuild inventory. It also lists friction and Kolene steel plates, a filter, front and reverse bands, a bushing kit, gaskets, seals, O-rings, and a modulator for a broader component-sourcing workflow.

Raybestos Stage 1 friction plates and Kolene steel plates supply the listed clutch and steel components, while the front and reverse bands expand coverage beyond the friction pack. The washer kit and bearing kit add further service items for a rebuild, and the filter, bushing kit, and modulator extend the inventory. Premium Transtec gaskets, metal-clad seals, sealing rings, O-rings, and rubber piston seals support reassembly. Its stated application is Chevy GM TH400, so use that compatibility when assessing the transmission.

Skip it if you need a stated model-year span for fit selection; the Transparts Warehouse high-energy Level 2 kit lists TH400 coverage from 1965–1995.

This suits a Chevy GM TH400 rebuild where the added washer kit, bearing kit, and reverse band are useful to the parts plan. Use the stated transmission compatibility as your fit boundary; no model-year span is supplied here.

#2 · Best Deluxe Kit

2. Raybestos Stage 1 Deluxe

• Weight: 11 lb

Best for: Raybestos Stage 1 overhaul.

Why it ranks #2: This Raybestos package includes Kolene steels, filter, band, bushing kit, sealing parts, and modulator, providing substantial coverage for a standard overhaul.

Raybestos Stage 1 friction plates paired with Kolene steel plates give this TH400 rebuild kit a clearly specified clutch-and-steel core. The included filter, band, bushing kit, sealing rings, metal-clad seals, gaskets, modulator, O-rings, and rubber piston seals extend the parts coverage for a broader overhaul.

The Raybestos friction plates and Kolene steel plates provide the main friction-and-steel components, while the Premium Transtec gasket kit and metal-clad seals cover sealing needs during reassembly. A filter, band, and bushing kit add supporting service parts to the package, reducing the need to source those listed items separately. The modulator, sealing rings, O-rings, and rubber piston seals round out the inventory. This is a Stage 1 kit, not a listing of every possible transmission component.

Skip it if you need a washer kit and bearing kit in the listed package; the Chevy-compatible Raybestos Stage 1 Level 2 kit adds both.

Choose this for a TH400 rebuild centered on Raybestos Stage 1 friction plates, Kolene steels, and a substantial set of sealing and service parts. Review the listed contents against your planned overhaul, especially if washers or bearings are required.

#4 · Best Raybestos Master

4. Raybestos Stage 1 Master

• Weight: 8 lb

Best for: Raybestos Stage 1 master rebuild.

Why it ranks #4: Its Raybestos Stage 1 frictions and Kolene steel plates are paired with sealing rings, metal-clad seals, gaskets, modulator, and rubber piston seals.

Raybestos Stage 1 friction plates paired with Kolene steel plates give this Transparts Warehouse master rebuild kit a specified clutch-and-steel foundation for Chevy GM TH400 transmissions. The package also lists sealing rings, metal-clad seals, gaskets, a modulator, O-rings, and rubber piston seals for reassembly work.

The Raybestos Stage 1 friction plates and Kolene steels form the core listed rebuild components, while the Premium Transtec gasket kit supports sealing during assembly.

Its listed contents do not name a filter, band, or bushing kit, so compare the inventory with the complete scope of your rebuild.

Skip it if you need a filter, band, and bushing kit in the package; the Raybestos Stage 1 Deluxe kit from Transparts Warehouse lists all three.

Pick this for a Chevy GM TH400 rebuild centered on Raybestos Stage 1 frictions, Kolene steels, and sealing components. Check whether your work also needs a filter, band, or bushings, which are not named in its inventory.

#5

5. Mivolox High Energy Master

• Weight: 1 lb

Best for: 1964–1998 TH400 applications.

Why it ranks #5: This master kit lists high-energy friction plates, steel plates, gaskets, seals, O-rings, and supporting service parts, with stated 1964–1998 fitment.

A stated 1964–1998 compatibility range gives this Mivolox TH400 master rebuild kit a broad, concrete application window. Its high-energy friction plates, steel plates, gaskets, seals, O-rings, and supporting service parts are assembled as an overhaul pack for G M Turbo 400 automatic transmissions.

The high-energy friction material is described as maintaining grip under varied load and temperature, connecting the friction plates to demanding operating conditions. Steel plates accompany those frictions, while gaskets, seals, and O-rings cover sealing components during gearbox disassembly and reassembly. The listing says the kit helps address slipping, harsh shifting, and delayed engagement. Its stated fit is G M TH400 models from 1964 through 1998, a range buyers can compare with their transmission before selecting the kit.

Skip it if you need a listed filter and pump or extension housing bushings; the Transparts Warehouse Level 2 master kit specifies those components.

Consider this for a G M TH400 within the stated 1964–1998 range when high-energy frictions and a broad sealing pack suit the rebuild. Its component list is general, so match the supporting parts against your planned work.

#6

6. Alto Less Steel Level 2

Best for: High-energy less-steel rebuild.

Why it ranks #6: Its high-energy friction kit includes a front band, filter, modulator, pump bushing, and extension housing bushing, and lists 1965–1995 TH400 fitment.

High-energy green friction plates and a less-steel configuration distinguish this Transparts Warehouse Level 2 TH400 kit. It also states fit for 1965–1995 TH400 transmissions and lists a front band, filter, modulator, pump bushing, and extension housing bushing for a broader service-parts package.

The high-energy green friction plates are the specified friction material, while the less-steel format keeps the package focused on frictions rather than a listed set of steel plates. Its front band, filter, and modulator add named service components, and the pump and extension housing bushings broaden bushing coverage. Sealing rings, metal-clad seals, gaskets, O-rings, and rubber piston seals support reassembly. The stated fit range is 1965–1995 TH400, which provides an application boundary to check.

Skip it if you need steel plates included with the rebuild kit; the Transparts Warehouse high-energy green Level 2 master kit lists steels.

This suits a 1965–1995 TH400 rebuild where high-energy green frictions and the listed band, filter, and bushings match the plan. Its less-steel configuration means steel plates must be handled separately if required.

#7

7. Raybestos Red Less Steel

• Weight: 4 lb

Best for: Raybestos Stage 1 less-steel kit.

Why it ranks #7: This Raybestos Stage 1 option includes friction plates, sealing rings, metal-clad seals, gaskets, modulator, and rubber piston seals, but no steel plates.

The less-steel configuration is the defining choice in this Raybestos Stage 1 TH400 rebuild kit: it lists red friction plates and sealing parts without steel plates. That makes its inventory relevant to rebuilders sourcing the friction components and seals while handling steels separately as needed.

Raybestos Stage 1 friction plates supply the specified friction material, while the listing’s less-steel designation clarifies that steel plates are not part of the named inventory. Sealing rings, metal-clad seals, gaskets, O-rings, and rubber piston seals support transmission reassembly, and a modulator is also included. The Premium Transtec gasket kit adds a named gasket component. Since the kit does not list a filter, band, or bushings, buyers should account for those parts separately when required by their rebuild plan.

Skip it if you want steel plates included with Raybestos Stage 1 frictions; the Transparts Warehouse Stage 1 master kit lists Kolene steels.

Choose this less-steel kit when Raybestos Stage 1 red frictions and sealing components fit your TH400 plan and you are sourcing steels separately. Its listed inventory also omits a filter, band, and bushings.

#8

8. NineEcho TH400 Master

Best for: 1968-and-newer GM TH400/3L80.

Why it ranks #8: The listing specifies GM TH400/3L80 compatibility for 1968 and newer and describes seals, gaskets, and necessary hardware, but gives fewer component details.

Compatibility with 1968 and newer GM TH400/3L80 transmissions is the clearest selection point for this NineEcho master rebuild kit. Its description identifies seals, gaskets, and necessary hardware as part of a complete overhaul package, offering a defined transmission family and year threshold for application screening.

The stated fit for GM TH400/3L80 transmissions from 1968 onward gives buyers a specific application boundary to check before planning the rebuild. Seals, gaskets, and necessary hardware are identified as included essentials, connecting the package to restoration and reassembly work. The listing also describes premium durable materials and precision-fit design, but does not itemize friction plates, bands, or bushings. Review the named contents against the parts required for your particular overhaul rather than assuming unlisted components are included.

Skip it if you need named friction plates, bands, and bushings; the Transparts Warehouse high-energy Level 2 master kit lists those components.

This is a candidate for a GM TH400/3L80 from 1968 onward when the listed seals, gaskets, and hardware fit your overhaul needs. Its component descriptions are broad, so verify the required parts against the supplied inventory.

#9

9. Phoenix TH400 Master

• Weight: 1.76 oz

Best for: TH400 master-kit shoppers.

Why it ranks #9: Its title identifies a TH400 master rebuild kit for 1965–1990, but the supplied listing does not detail the included parts.

A stated 1965–1990 application range is the clearest differentiator of this Phoenix Transmission Parts TH400 master rebuild kit. That span gives owners a concrete starting point for checking application, while the title identifies it as a master rebuild kit rather than a gasket-only set or a less-steel rebuild option.

The listing identifies the product as a TH400 Turbo 400 transmission master rebuild kit and specifies coverage from 1965 through 1990. Those details help narrow an application check, but the supplied information does not provide a component inventory or friction material description. Buyers should therefore treat the title and stated range as the available selection details, then assess whether the kit’s contents suit their planned rebuild before relying on it for a parts list.

Skip it if you need a named parts list before choosing; the Transparts Warehouse Stage 1 master kit specifies Raybestos frictions, Kolene steels, seals, and gaskets.

This may suit a TH400 owner whose transmission falls within the stated 1965–1990 span and who can evaluate the kit contents separately. The supplied details do not itemize components, so it is a limited basis for planning a rebuild.

#10

10. Mivolox TH400 Gasket Set

• Weight: 1 lb

Best for: TH400 gasket-set sealing work.

Why it ranks #10: This is a gasket-focused set with paper and rubber gaskets for 1965 and later TH400 transmissions, not a complete friction-and-steel overhaul kit.

Paper and rubber gaskets are the defining contents of this Mivolox TH400 gasket set, giving rebuilders a focused option for transmission sealing work rather than a friction-plate overhaul. The listing states compatibility with 1965 and later TH400 models and describes precision-cut gaskets intended to help prevent fluid leaks.

The combination of paper and rubber gaskets covers two gasket material types in one set, supporting a sealing-focused rebuild workflow. Mivolox describes the gaskets as precision-cut and intended to create tight seals, which connects the set to fluid-leak prevention during transmission reassembly. Its stated compatibility is for TH400 Turbo 400 transmissions from 1965 onward. Since the listing describes a gasket set, it should be selected for gasket needs rather than treated as a complete kit with friction plates or other overhaul components.

Skip it if you need friction plates, steels, and a front band; the Transparts Warehouse high-energy Level 2 master kit lists those overhaul parts.

Choose this Mivolox set for gasket replacement or sealing work on a TH400 from 1965 onward. It is a focused gasket option, so plan separately for friction plates, steels, bands, and other overhaul parts.
