I have a 98 ZJ with the 4.0 and its having a slipping problem when it shifts from 2nd to 3rd. Now it will on slip if you drive it normal but if you give it a good amount of throttle it shifts perfect. I have replaced all of the sensors and new fluid and filter. I have even swapped transmissions and it does the same exact thing as the first transmission. Is there anything I might have over looked that would be causing this issue in 2 different transmissions now?

 

possibly the pcm?

 

Does it kind of surger between the gears? Mine seems to be doing the same thing as yours. So far I figure I would drive it as is.

 

That's what I was possibly thinking.

 

Yeah it has a surge when shifting from 2nd to 3rd. I still drive mine everyday but its really annoying.

 

Anyone else might know what's going on?

 

Are u swapping the old sensors and such off one tranny to the next if so might possibly be one of them going out.

 

You might have low governor pressure. That shift it done electrically and is controlled by the TCM.

 

n00b here, but years ago I had a 2001 B Van with a 904 trans in it and it did the same thing for about six weeks before finally deciding to say bye bye. It didn't explode, it just decided that it wasn't going to go into any gears at all.

Since I wasn't the one paying for maintenance/repairs on it, the transmission was rebuilt in it but I think it was probably the governor/shift solenoid.

 

Nope swapped all new sensors into the tranny I just put in.

 

Is the TCM integrated into to main PCM? I looked under the dash for the TCM and couldn't find it.

 

My 95 ZJ 5.2L automatic transmission is slipping after driving if i shut it off for a minute and start back up I can drive it again sometimes feet sometimes miles please help

 

Welcome to the forum.

The FSM has a great transmission diagnostic table for the 46RH transmission in your vehicle.

Has the fluid level been verified properly?

This topic shows my 46RH rebuild that may show useful information.
