Looking for guidance on automatic transmission upgrades
Howdy DTR.
I have recently trading in my manual for an automatic transmission. I just couldn't take sitting in traffic for an hour every day with a dual disc clutch.
I am looking for some guidelines on automatic transmission upgrades. All the research about diesels I've done up to this point has only been about manuals.
My goal for this truck is a reliable 500hp daily driver. I plan on the following mods
Smarty SR
Garrett ball bearing turbo
Airdog II
F1 injectors
6in lift with 37in tires
...not necessarily in that order. I just want to know just how much I need to spend on the transmission to support my goal.

better plan on replacing the front & rear end gears w/37's & 6 inch lift
it looks like a really nice build plan until you read the last mod
the 37's & 6 inch lift are not going to help the life of the transmission or driveline
at 500 rwhp the tq converter , valve body will be a good start , you may have to upgrade some hard parts in the transmission , a lot also depends on how you drive the truck etc

48RE 373 gears w/ 37 inch tire
70 mph 1636 rpms in OD
60 mph 1403 rpms in OD
35 inch tire = 70 mph 1730 in OD
= 60 mph 1482 in OD
33 inch tire = 70 mph 1834 in OD
= 60 mph 1572 in OD

So torque converter and valve body, check. What are the "hard parts" you are talking about in the transmission? Is it better to build it up piece by piece, or should I just start saving to buy a fully built transmission?

Drop the coin now and get a full billet. I skimped in the beginning, and broke mine. (my fault)
Goerend is the best name right now in transmissions, but I have had zero problems with my ATS, and love it.

Flex plate,converter,valve body,billet input,clutches,ect..
I would suggest finding a major builder in the area and talk to them about your needs like Hotroddiesels.com

agreed with the above statements running the big tires i would prolly get a billet output shaft as well your looking at about 5-6 grand for the above. id get a tripple disk,converter billet input/output, flexplate, cluches, servos, vavle body etc etc the list goes on and on.

I just upgraded my 48RE with DTT parts. Triple disk torque converter, all clutches, bands, billet input shaft, valve body and flexplate. It is amazing how quick the truck is now. i am very happy with it. James Northum did all the work. His shop is James Transmission Tech in Midlothian Tx, which is just south of Dallas. That's not too far from San Antonio. It might be worth your time give him a call. His number is 972-467-3702. I believe he is the only DTT certified installer in Texas.
