2000 Dakota Transmission

I posted a message previously on another thread regarding my tranny.

Seems to slip, RPM bounce when shifting into and while driving in high gear. Seems to get worse as I hit bumps in the road.

I have a P0505 error code and a P1281.

I cleaned the IAC with carb cleaner and this is when the shifting problem seemed to start. However, yesterday was much colder than usual and there was no signs of slipping. Could the problem be thin tranny fluid?

I haven't replaced the IAC sensor as of yet, my local autoparts store didn't carry it, so I may have to go to dodge.

Any help, suggestions are greatly appreciated.

Sound like you have trouble with your throttle position sensor (t.P.S.)L had the same problem last year l also thought it was my tranny this part cost about $50 bucks l would try this before spending 1000. To 3000. This is very easy to replace yourself hope this helps you

Thanks for replying to my post,

What were the circumstances surrounding your T.P.S. Problems?

Mine seems to happen more in warm weather and is isolated to high gear usually around the 2000 RPM range.

It makes sense that it could be the TPS as it seems to react most to changes in speed/throttle.

Thanks again.

I was having the same problems you are describing, I took my truck to the transmission experts and had my tranny replaced but that did not correct the problem, I had a friend who checked my truck out and suggested that it could be a sensor. I checked the internet and found out that many people had problems with their tps, so I changed this and it solved my problem.

Going to get my TPS sensor today after work. Any tips on installing it? I looked at the tranny the other day and there seems to be several sensors attached to it.

The problem is getting worse, now the truck will up shift at odd times and just seems to run horribly.

I have been doing alot of research on the problem and discovered that the torque convertor is locking and unlocking causing the tranny to shift up, down and rpms to rev.

It does seem to be common, but I'm wondering if there are other issues along with the TPS (ie: solenoids that are bad also) I will start with the TPS and see where I get with that.

I hope this is the miracle fix!

Installed my TPS yesterday, and the problems are gone. I can't believe such a little part can cause so many symptoms, I thought for sure my tranny was toast. Pheeeeeeewwwwwww!

Very easy replace also, did it in 5 minutes in the parking lot of the parts store. (Once I learned that the sensor is actually on the throttle body and not on the tranny as I first thought).

Thanks.
