Transmission Rebuild Kits

This kit was put together to assist you with that high mileage rebuild. When your transmission has reached its limit of efficiency and smooth shifting, it’s time for that rebuild. Here at BAKER we have assembled the kit to assist you with this rebuild and make it as painless as possible. Kit includes all seals, bearings, snap rings, gaskets, and retaining nuts needed to completely rebuild your stock or BAKER transmission. 


This kit, after installation, will help reduce bearing noise with new high-quality bearings. Let’s not forget the gaskets and seals in the kit, to help stop all of those annoying leaks. You will end up with a quieter, smoother transmission after this installation and rebuild.

*We do offer a transmission rebuild kit for Thunder Mountain transmissions but since the transmission is very complicated, we recommend that you send in the transmission to BAKER Drivetrain or have a Thunder Mountain professional rebuild the transmission. If you'd like to purchase the transmission rebuild kit for a Thunder Mountain (PN TRK-TM), please place your order at 517-339-3835.

Not happy with ordering process

Paid $ 96 extra for 2 day delivery. Parts where ordered on a Wednesday. Did not receive parts (trans rebuild kit order # 11061) till the following Wednesday, a week later. This put me behind on other scheduled repairs. I should of been refunded the 2 day delivery fee, which came out of the profit on the job. I will think twice before ordering from Baker in the future. The rebuild kit was of good quality, but the process of ordering and receiving them was not. I had to take the 2 day delivery fee off of the customers final bill. So the fee came out of my pocket, I'm not very happy about that.

Very Disappointed

Purchased and installed the DD6 in 2010, with 80K miles on it and 5th gear started making a lot of noise. Ordered a new 5th gear set with a rebuild kit only to find out that not only does Baker not service their gear sets but called every one on the Bakes web site for service and not a one of them could rebuild the gear set either. Conclusion as far as I can see it is a throw away gear set if something goes wrong. Question, why did Baker sell me parts if no one can rebuild it? That being said, everyone was certainly nice but technical support, Linda twice gave me incorrect information and Steve bent over backwards to help. I ended up retuning the parts and purchasing another DD6 gear set. End result, it's a great gear set until you have a issue with it.

Baker has a great product, but...

1. I am a newby, never did any in depth mechanical work and (it appears) that I was able to successfully rebuild a Baker 6 speed that had detonated after trap door bearings went out 2. It was likely an 02 Baker build and the rebuild kit was great, but had wrong sized bearings for my build 3. Took an honest months of back and forth to get right bearings 4. Also the mail seal and spacer were the wrong size and that still hasn’t been addressed even though they said they would issue a return authorization for it and send the correct ones Just kinda gave up the bearings took so long.... So, I don’t know what that might mean to someone else....
