help its slipping

[mopar marc]

Hey guys I am having one of those weekends I swapped out the valve body on my power wagon today (it was shifting to harsh into third) so i get it all back together and take her out for the first few miles it worked great then started slipping not when it shifts only when you start out forward or back when you drop into gear it is very slow to go what the hell have i done? the fluid level is good (maybe a little high) also could not get it to shift into third but i figure i just need to adjust the linkage as i did not go over 45 any help woul be appreciated the trans was rebuilt less than a year ago and worked good until i screwed it up. also the valve body is stock and new.

If you for sure tightened up everything and did nothing else but swap out the valve body it sounds like the new valve body is defective. Kinda sounds like possibly a pressure regulator problem.

If you have a pressure gauge and manual you can run pressure checks on it to see what the pressures are. That will indicate what is happening. If you don't have a gauge drop the pan and visually look things over to see if anythings loose. If you don't see anything I'd tend to think it's a stuck pressure reg. valve.

It's always posible that in the manufacturing process of the valve body a piece of metal didn't get cleaned out good and came loose and got lodged in the pressure regulator valve after you drove it a couple of miles so it may not have been anything you caused at all.

thanks for the reply is the regulator in the valve body?

Your welcome and yes it is. It's the 2nd valve in front of the manual shift valve. There's 2 valves covered with a metal plate that sticks out and is screwed on with about 3 or 4 screws. The valve closest to the manual valve is the pressure reg. valve. Actually all you see is the spring sticking out. The valve is inside. By the sounds of things what would be best is to remove the valve body and make alot of rome on a large bench and carefully one at a time remove all valves and clean everything. Make sure and don't get anything mixed up. It's very easy to do. It might be best to make a diagram as your disassembling it if you've never done one before. Then re-assemble and you should be good to go. Remember cleanliness is next to Godliness when it comes to transmissions. A chunk of lint from a shop towel can even cause a valve to stick.

I replaced the valve body and now its fine but I still want to salvage the other valve body so I will do what you say I have never done it but only one way to learn thanks again

Glad you got her going Marc. That's the way I learned too. Just tear in to it.
