When i am on the freeway, between 50 and 60 mph i get a surging under normal accelerating. But at wot there is no surging. I hope this is the tps, i just wanted a second opinion before spending the money.

 

did the CEL come on ? before you get gun ho about it take to autozone or who ever and hook a scanner up , maybe a stored code is in there.. maybe your TQ converter is not locking check fluid ? when was the last time the tran fluid was change and filter ?

 

the cel did not come on. and they checked the fluid when i got the oil changed yesterday. And i have had the truck for one year and i have never changed the fluid. I did not change it yet because i bought it from a dodge dealer and asume they did it before i bought it.

 

i have the same problem on my 02 2500 ive been told its the tps and its actually at the dealer right now being replaced along with my tranny

 

are you paying for the tranny replaced? Because from what i have read on here the TPS is supose to fix the problem.

 

when it happened to me a gave the iac a good cleaning and it went away.

 

whats the iac?

 

My experience:
Problem was surging while maintaining consistent highway speeds.Tach jumped 300-400 rpm. No surgewhen accelerating.

Solution was TPS. $80 part for the V10. 15 min. to install. Child's play.

 

95% chance it is the TPS. For the 5.2 it is $35 at O'Reillys or Auto Zone......Takes 5 minutes to change it. If not fixed - it will overwork and trash your tranny. Ask the two dealers that never diagnosed the bad TPS on mine and rebuilt my tranny under p-train warranty......

The iac (Idle Air Control) will cause surging at IDLE if it is dirty or bad - not at cruise speed.....

 

thanks for the help everyone, im gona get the tps replaced asap
