hey guys im having one heck of a problem, it's going to be a long story to get all the facts in so here goes:

ive got a 2000 dodge ram 1500 4x4 with the 360, 392's 35 inch tires
cold air intake

one friday night after a few to many beers in buddys shop we got the idea we could get some smoke shows goin, well i jumped in my truck and tried to get my big 35's turnin an well i blew the diff out.

SO, over the next day i rebuilt the diff threw it back in and thought i was good to go, jumped in to drive away and this truck is boggin down and locking up the diff, i couldnt get past 40k without skidding to a stop, i figured it was the diff, re did it and same thing, i would get to usually 30k @ 2000 rpm it would bogg to 1500 no matter how much throttle i gave her then full lock up and tires would skid me to a stop. it's like it locks and unlocks it never lasts more than 3 seconds and i have all my gears ( i think) i never make it out of first before it locks up on me

So i popped of the driveshaft figuring i had a piled up chain in the transfer case and yup did it again so popped out the transfer case getting ready to rebuild it when buddy comes by with a code reader and what do ya know it keeps doing the same thing without the transfer case on now only because i have no drivetrain i keep bogging out the motor, it wont stall but @ the rpm where it sits at 30km it wont get past, usually i hit 2k an boggs me down to 1500 or lower.

so now i figure it in the tranny and i popped a couple code which are:
P1740: TCC or O/D solenoid perf
P1757: Gov Press above 3 PSI in gear with 0 MPH
i think it's a 46re, maybe 47re transmission

And now im lost because i dont know transmissions at all.
ive had a couple people tell me its the torque converter and i spoke to my buddy who's dad is a tranny guy an he says it looks like to him that the tranny is going into limp mode and says to replace the governor pressure sensor.

if you guys have any advice it would be greatly appreciated,
feel free to pm as well

 

Im confused, did you pull the rear driveshaft out and then try to drive the truck with front wheel drive only? if so,did the rear end still lock up?? it sounds like you've lost a tooth from your ring and pinion and it binds up at that spot sometimes..

 

No no what I did was drove it with everything installed an it kept locking up so I pulled out the driveshaft and transfer case to rule out the rear diff an transfer case an to see if it was the transmission an it was because it kept bogging down while in drive without the driveshaft and transfer case

 

ok,I see, have you tested it in all the gears and does it behave the same? hopefully some tranny guys can chime in on this?

 

Wonder if you have a clogged cat....... that would account for the engine bogging at low RPM, and not wanting to go over.

It's *possible* you smoked the trans, but, I would check the cheaper stuff first.
