Next Gen Drivetrain, Inc.

"Took a little longer than expected to receive my unit but once installed they were very communicative and always willing to answer questions or concerns. Now I’ve put 1500 miles on this thing and finally got to push some power through it after the break in period was done and I’m very satisfied with the performance so far. This thing makes my 2021 gmc 2500 l5p shift like a sports car, firm confident shift and very quick at that. It’s like there is no downtime between shifts like the stock unit. Looking forward to putting thousands of more miles on this thing with a smile on my face!"

"Bought the 10R140 cherry bomb for my F-250, was actually a very simple install and saved me some money. Nat at Next Gen gave me all the support I needed and when I needed it. Great customer service and support. Thanks guys for a great product and support."

"I have a 2013 Durango rt with a 65rfe that had horrible shifting issues. No passing gear.and pore downshifting. After reading the tech article from Next Gen. I purchased there complete valve body and followed what they recommended on replacing during the install. After i install the valve body and took it on a ride I instantly felt the improvement. The shifts are firm and the downshifts are on point. It feels so instant and the power is direct now like the motor isn’t pushing threw the trans now. Im extremely happy with there product really does fix the shifting issues with this trans."

"I ordered the project carbon valve body for my 1999 Ram 3500 with the 47re. They took the time to call me and make sure I was getting the right pressure transducer because Ram switched styles half way into a specific year. The product is very well built. My truck shifts smooth and solid now with no issues at all. I called to ask technical questions and they were very helpful for for install. I’m just waiting for my core charge back now, but I’m definitely going to get the Project Carbon Valve body for my 2018 Ram too now. Customer service was excellent."

"When in need of either a rebuild or a new trans to replace my 68rfe I called many places inquiring many things. Also while doing research on the 68rfe. I went ahead and started sourcing parts to make it a DIY project from home. Ended up Calling Nextgen and had a great conversation with Nate. Coming from a heavy career in motorsports and engine building as well as CNC machining...Nate told me everything I wanted to hear. I'm running Nextgens Valve body, pump and a 2 disc billet converter. Parts came in earlier than expected and man were they beautiful parts. Returned cores and core charge was returned as agreed. I waited a little bit to do this review as I wanted to see the transmissions functions and stack some miles on. I've got 3,000 miles on everything now. Drove loaded with 20k pounds through the Appalachians with no skip to the beat. Now time for a fluid exchange and to keep trucking. Thanks Nate!"
