I'm new here and relieved to see there is some information on this vehicle. I acquired a 2000 Taurus SE with 167K on it from my grandfather who passed away. It has the Vulcan engine and AX4S transmission I guess. When I found the vehicle, it was covered in and packed full of stuff. It was buried with 4 flat tires for 6 years in a garage. I had heard it had a "blown engine" and the "trans is junk", but nobody really knew.
Needless to say, I have replaced the fuel pump and the engine is currently running again, but when I went out to drive it, it has some tranny issues, so I'm trying to see if there is an easy fix for it .
I know this isn't exactly an uncommon problem and I've read numerous threads similar to it, but I'm looking for more of a solution. Looking at the tech manual for the tranny, it appears that it could be around 5 different things from VSS
, shift solenoids, etc, but I'd rather ask people with experience on the matter.
Here is what I have:
The car if it is "1" drives perfectly fine. I can mash it and spin the tires with no slipping and it will drive all the way through that gear perfectly fine. If I let off the gas, it will engine brake...just as it should. "R" is also fine. The problem lies in "D" and "O-D". Whether I hammer it or go gently, is irrelevant. It will drive up to 20-30mph, then completely let go and rev out with no power going through the drivetrain(it doesn't accelerate).
It's not an engine issue. There are no abnormal sounds when it drives or "let's go"...no slipping or anything...it just let's go. It simply gets to 20-30mph then revs out without acceleration. It feels like it's reached the 2nd gear shift point, and the tranny is suppose to initiate the change, but either mechanically can't or it's not getting the proper information to do so. Transmission fluid level is adequate and the color is tolerable. The speedometer "works", but it is kind of odd how it stays put while I'm accelerating for a couple tenths of a second, then begins to work...I don't know if that's normal or not with this vehicle.
My question now is what am I looking for? Would it be a simple VSS
change out and it would fix it, despite the speedo "working"? I don't know how the TPS
relays information and whatnot. Am I looking at something in terms of bad connection/wiring, or a bad fuse on either fuse box? I'm just at a crossroads. If it's fixable for a tolerable amount of money, then I'll go ahead and get it fixed. If not...I really don't know.
