I have 135,000 on my 5.9L diesel and my automatic transmition has started slipping all the way through 2nd gear. Is it time for a rebuild or something else i could try?

i aint sure what automatics they use with cummins engines, but if its a chrysler tranny you should either rebuild(not just to stock specs.) or trash and get an allison.

Dont go to chrysler to have it fixed. U need to contact http://www.dieseltrans.com/dodge/transmission_components.htm and ask them for the closet dealer to u. I belive he is right north of denton. James nothern or somthing like that. U wont ever have a problem.

Ur clutches are shot. chrylser reman wont last. Money better spent on an aftermarket one.

Thanks.

dont know where you live but i weatherford there is a shop called texas diesel power if you can head out here talk to john and he will tell you what is best and do good work

John does awesome work too! I forgot bout him

As time goes by that slipping will get bad enough the truck will barely move. Right now you are losing power and mpg w/ that convertor. I work for Cummins, and my service truck and personal truck both require a new converter every 80k miles and a trans rebuild at about 120k miles. The trans are the weak spot. It is best to go to a reputable diesel shop that does transmissions. Have them install an aftermarket torque converter. The $$$ you save will allow you to upgrade the trans to the point it will never blow again.

Southern Plains?
Hows yalls business? I run a service truck for Peterbilt...we've been kinds slow latley...

My stock converter was shot at 15k. Im on my 3rd at 48k

What's up with them going out so soon?

more torque than stock can handle,had john at texas deisel put in bd convertor ,valve body and flex plate never a minutes problem! i'm not stock or gentle on it either ! give him a call you might not like what he tells you but it will be the truth!!! 817-594-9909

Yea i was hard on mine too. Lol Lots of 4wd launches and track runs.

Yes, Southern Plains. I actually work in Power Gen, we're doing great, but our engine shops and field service could be better. We're strong though.

86k and my torque just failed. the pump drive stub shaft broke. all the disc looked ok nothing burned up. it will cost me about 750 to repair. That's doing it my self. You would think they would last longer than that.

i have an 04 3500 dodge/cummins that just rolled over 100k miles and i drive it pretty hard. The only problem i've had is the a/c and one hell of a cracked dash.
