There is a rod that runs from the injection pump to the trans on the drivers side. it should move freely and there should be a spring that holds it forward so that it only pushes back when you push down on the excellerater.

Sounds like TPS (Throttle Positioning Switch) They develop "hot spots" or wear spots usually at throttle positions that are commonly used alot IE: cruising speed. When they get hot spots they fluctuate looking for solid connection. Replace TPS.

This problem could be one of several it is hard to pin point the car needs to be hoisted up and checked out further for torque converter which is between the motor and transmission or it could be a internal transmission valve this is why it needs to be hoisted up preferably at a transmission specialist.

No power and will not shift untill warmed up in cold weather also pushes a lot of light blue exhaust untill it warmes up.can you tell me what is wrong?

nothing.... it's a diesel. transmission compensates shift point for higher rpm to assist in warm up. start it up and have a coffee. than drive..

My automatic transmission on my 04 Dodge Diesel 2500 4x4 with 104k miles is acting up. It will not shift from 1st until you back out of the throttle then it shifts. If you get back into the throttle a...

you want the simple answer....its a Dodge, i drive one to, but its true....

complex answer has much more to do with the size of the holes within the transmission where the fluid flows, the clogg up easily with the older fluid, and the seals and bands cant handle it

things you can try

cheapest: fluid and filter, and throw in a bottle of lucas oil for transmissions, this will settle this down some and the lucas oil help for smoother shift

more expensive: fluid flush at a shop, this will do the same thing as a fluid change, but it changes all of the fluid, where as a regualar fluid change only gets about 3/4 new

most expensive, get a rebuid, ultimatly you will have to replace this transmission in the future, you can try the other swteps first and they may help for a while but once a transmission starts going downhill you can slow it down but you cant stop it.

Transmission is not operating correctly when cold. The RPM's are above normal operating levels prior to shifting. After the vehicle travels a couple of miles, all is fine. Normal operational RPM's are...

The PCM is allowing torque converter slippage until the transmission reaches normal operating temperature because cold transmission fluid is a drag on the engine and causes it to burn more fuel.

Transmission- 2001 Dodge ram 2500 diesel 4X4

I have a 2002 Dodge Ram that doesn't like to shift into 2nd when flooring it from a Stop. Imagine if you were to floor the gas in neutral, the engine REDLINEs and the engine governor kicks in to keep the RPM from blowing the engine......while stuck in first Gear. If i let off the gas, it goes into 2nd fine. I have replaced the Speed Sensor on the transmission ($18) and it seemed to fix it for one day. After 200 miles, its doing it again. ANybody have legitimate answers in here? Its only got 60K
