My 1999 dodge ram 1500 5.9l 4x4. I’m still having Tran’s problems, when I’m driving the rpm gauge, keep bouncing/shifting late, I used a tuner to raise the rpm limit, fixed the problem for a while, then my truck stops getting power to the wheels. I pull over let it sit for a bit, and I can drive again, WTF is wrong

 

Might be TPS. Might be pressure sensor and solenoid in the trans.

 

elaborate, please picture, ect what Im looking for. How can you tell its bad ect

 

Is this one of the parts needed

TPS is on the drivers side of the throttle body. Throttle position sensor. Need a meter, or scanner to test. (or, simply replace it, and see what happens.)

(governor) Pressure sensor and solenoid are IN the transmission. Drop the pan, and they become visible. They are rather notorious for screwing up..... only way to really test them, (if you aren't getting codes for 'em) is to dig in, and inspect.

 

I think that is the fourth gear shift solenoid, and that is for a trans without locking torque converter, so, no. Not the one you want.

 

Im pulling No codes. Could it still be the TPS

 

Yep. Do you have a voltmeter available?

 

have you tried the key dance trick to try to pull codes?
