2002 auto trans problem

ok... i got a 02 ranger 4.0 auto... and the trans is getting worse and worse, in between 2nd and 3rd gear it slips and the truck revs up and then goes into 3rd. another thing, every once in awhile when i slow down to a stop the trans dont shift down and it will be in like 2nd or 3rd gear, then it will kinda start shifting down while im stopped and it jerks the truck a lil. my dad talked to a guy he works with and he said that ford trans are/were known to have a seal go out above the trans filter, has anyone else heard of this, or have any ideas that could help me out??? thanks for your time

Sounds just like the problem with my 01. Turned out to be a bad seal on the valve body, they took care of it under warranty. I've heard it is a common problem with these transmissions.

I've never done it myself, but I have heard it's doable for someone with a little bit of mechanical know-how. You are going to need the Valve Body Service Kit (3L5Z-7M203-JA) and the Valve Body Separator for your application (looks to be 1L5Z-7Z490-BA). See:

Hey Seth, please let us know if replacing the gasket fixes your tranny troubles. I have a 2001 3.0 auto and am curious about some of the tranny problems and solutions people have with them. Thanks.

I own a 2002 with a 3.0 engine.

The transmission had the same complaints at under 10,000km's.

After 6 attempts it is now working good.

Valve bodies are a real problem area.

The first time mine was fixed they just replaced the gasket. 6 months later they replaced the valve body, all has been well for over 30,000.

Seth, there is no valve on the throttle body that has anything to do with the
transmission pressure.
