I have a 1998 dodge ram 1500 i just bought, I had to add a catalytic converter and two O2 sensors that it didn't have and now when i turn it on i can drive a few blocks and then it doesn't want to shift in to second for about a minute or so then it kicks in and everything is fine. I already replaced what a diagnostic machine told me to it said i needed a new governor pressure sensor and after i replaced it, the trucks still doing the same thing. If any one has any ideas it sure would be appreciated thanks, Wes

 

Did you replace the Gov solenoid as well, or just the pressure sensor?

 

just the sensor but now im thinking the solenoid was the problem

 

Yup, and remove the Gov body also and clean it. The solenoid is more common to go bad/get clogged. If it does the same thing after replacing it, then you'll atleast know you have a different problem. And get one of these to replace it. http://www.doghousediesel.com/catalog/i307.html

 

Also check TV cable for correct adjustment and check TPS. A number of things can adversely effect trans shifting.

There is a service manual in the FAQ/DIY section that you can download.

 

Zman you're lettin him down he just added he put on a new cat and o2 sensors and no mention of the plenum????? What's going on right now haha anyways check the sticky at the top of the page otherwise your cat is gonna clog up again

 

Yea I know, plenum is probably bad, but since we know the cat is not clogged, it has nothing to do with his shifting problems right now.

 

so i replaced the solenoid too and its still doing the same thing, im losing my damn mind, what do you guys think it could be

 

Did you try the check valve delete?

 

I have beat the dog spit out of the tranny pan on my Acclaim-driving over the extremely rough and rock-strewn road to my home site, so it leaks about a quart a month. I know it's time to add tranny fluid when, on cool mornings, it won't shift into 4th for about a minute. Then, after warming up, it shifts normally until the next cool morning or I add a quart of tranny fluid. Not trying to be insulting, but have you checked the tranny fluid when the engine and tranny are HOT and the tranny is in neutral?
