Hey guys,

Wow! It's been over a year since I've been on here. Busy, busy! Okay, here goes...

I just picked up a 2000 Ranger 4x4 with the OHV 4.0L paired to the 5R55E (if my research is correct) with about 140,000 miles and a 3" body lift. I bought it knowing it has transmission issues. I am going to make a small build thread and show my progress until I fix everything and then sell it. As for the transmission issue..

Truck starts up, no problems at all (other than a pretty significant misfire, codes P0133 and P1151, which are O2 sensor codes). Trans fluid is up to proper level, good color and possibly a slight burnt smell. However, while it is in "park", the truck seems to be slightly in "drive" if that makes sense. What I mean is that while in park, if you give the truck some throttle, it feels like you are power-braking the truck (foot on brake and accelerator at the same time) and sometimes the truck violently jumps forward a few feet, and goes back into park.

There is no reverse gear; with the gear selector in "reverse", the truck still moves forward as if it was in drive.

There is no neutral gear; with the gear selector in "neutral", the truck still moves forward as if it was in drive (exactly the same symptoms as "reverse" gear).

With the gear selector in "drive", the trans behaves normal but has a little hard time engaging into second gear. It kind of flutters in between them.

As for "1" and "2", they behave normal

I haven't driven the truck very far, maybe 5 miles at the most but doesn't seem to slip under hard acceleration.

To me, it seems like the shift cable is mis-adjusted? Possibly something to do with the 3" body lift? I am not too familiar with transmission problems, but have torn down and reassembled auto transmissions before. I was wondering if any one else has had these issues. I spend a while searching the forums and didn't find any similar problems. Any input is appreciated! Thanks!

Andy

I would start by making sure the cable is adjusted properly. Then go to the transmission range sensor. In my opinion, it sounds like the TR sensor.
