The dreaded tranns code... I have a 2000 dodge ram 1500, 5.9 gas, 46re. The problem im having is a recurring tranns code p1740. I bought the truck will 100k mi on it not sure if the transmission valve body pressure boost valve cover plate has been replaced (i read in a tsb something about some orifice not being large enough on the plate) 1 month after buying the truck the code popped up, luckily at the time i had a 1k mi warranty. I would have to let off the pedal and wait a second or to for it to shift. Took it to the dealer, they swapped out the 2 solenoids/filter/fluid.... Code = gone/no more symptoms.... 1 month later the code came back. The truck shifts fine, and has no symptoms at all. I've cleared to code multiple times, and the code come back with a vengeance after 30 miles..

Any ideas what could be causing this problem?

P1740 TCC or O/D Solenoid Perf

No symptoms you say? Shifts out nice? O/D works fine? You can feel TCC engage/disengage?

I would suspect that this is a symptom of another problem manifesting itself, but, as to what that problem is, I have no clue.

Something else to consider is, the dealer generally gives a 12 month/12,000 mile warranty on their repairs. Since your repair was done under some flavor of warranty, don't know if it would still apply. Best bet would be call 'em and ask 'em.

You might wanna post this in MonteC's trans thread, he is our resident trans guru.

 

yeah everything seems to be working just fine. Good idea about the warranty on work done. I'll call in the morning and see what they have to say for thems haha. i'll repost in Monte's.
