Great set!
Worked out great, no issues. Set in perfect, gasket sealed perfectly. 150 inch pounds (not ft pounds) and your good to go.

Gear quality, great fit
Comes in a nice box. The filters were good quality and fit perfectly on a 68rfe. My only complaint is the gasket was very tangled up. But I could still use it

Great!
Package arrived in good condition. Individually wrapped and sealed to prevent contamination. Fit 2018 ram 2500 6.7l with 68rfe perfectly! Gasket works well as well with 0 leaks. I actually had to remove the pan after about 100 miles after installing these (no relation to this kit) and reused the gasket and it hasn't leaked. Would recommend!

Excellent quality and perfect fit.
Installed the DOC’s Diesel transmission filter kit and couldn’t be happier with it. Everything fit perfectly and the quality of the filters and seals are pretty great. It came with everything needed for the service, which made the job straightforward and hassle‑free. This kit is a great value compared to dealership parts and doesn’t cut any corners. If you’re doing a transmission service, I highly recommend this DOC’s Diesel kit. I’ll definitely be using it again for future maintenance.

great product, easy to do at home.
my husband says this is perfect and exactly what he wanted. He did all the work at home instead of paying a shop and it seems it was relatively easy to do.
