how many miles? when was you last flush or drain and fill?

but sounds like jmod is your answer ,

10-4 ill have to try the j-mod i have slightly under 150k on the trans. It had a flush at 98k miles.

patman go check my build thread out. Ive got pictures up.

im on my phone right now but i will next time im on a computer.

150k is kinda high to be doing a jmod. drain the pan and fill the 4 or 5 quarts you drained out and see how the trans is acting after that. you might need to start saving your spare change for a new transmission

10-4 bud. im gonna have to build the transmission before i get the Cummins in there. Didnt plan on doing it this soon though.

thanks man. whats a good transmission?

you can have your 4R70w built but it wont hold the torque of a diesel for very long. you would be better off doing a manual or auto that comes behind the cummins from the factory.
with that in mind i will reccomend that you just do your drain, filter, fill for the mean time and you might be able to squeeze some more life out of it for the time being especially if tou are gental with it

well its not going behind a big deisel. Just going with a 4bt 3.9L Cummins ill be leavin the motor stock for the most part as well.

the 5.38 gears should help, ALOT with ease on it

yes regearing will help offset some stress, but you are still adding alot of weight to the truck.

do they make adapter bell housings to run your trans behind the 4bt? Have you thought that far ahead?

actually i have been trying to find one. Which i cannot. Someone told me that theres a company that will make me one for any application. Cant remeber what company though. Advanced Adapters maybe.

But for the price of that it might be easier to run the dodge trans. But how would i do that with our computer controled trans. I definitely dont want a manual.

Patman03SprCrw · #10 06-14-2009, 12:49 AM

just run the whole dodge engine and trans computer, and then youd have to custom wire in your gauges or aftermaket gauges

4.2trimble · #11 06-14-2009, 12:53 AM

ok that probably will be alot easier anyway. Id have to do get different gages anyway.

Im kinda thinking around $10k for Motor, Trans, tcases (203/205), fabrication and tuning. I think it will be close.

dont forget new driveshaft lengths, and maybe built DS if you have deep pockets

Are you saying it shifts sloppy, or the lever feels sloppy? If the lever feels sloppy, you have loose bolts inside the steering column.

yeah man, the shifter itself is sloppy. Just for instance ill put it in D hit the gass and its really in neutral. just to make sure im in drive i have to go all they way to the right (1) then bump it once (2) then bump it again (D)

I havent had it on the road yet so not sure how its actually shifting.

Got any diagrams on these bolts?

I'm afraid I don't, but I do recall seeing threads on this issue here. Something ain't right either in the column or down at the tranny. It's not an internal tranny issue.

On another topic, if you are planning on putting a 4BT in there, you need to research the engine redline carefully before you put 5.38's in there. Diesels generally can only be run to about 1/2 the RPM's of a gas motor, I think even with huge tires, 5.38's may be too low for highway operation. Just a suggestion.
