I bought a '97 GT Convertible with a 4 speed automatic from a private party. Runs great but will not shift beyond 2nd gear. I know little about this car aside from what the seller told me. Supposedly they swapped in a newer '01 GT engine with 40,000 miles on it recently. Are the computers between engine and tranny compatible between '97 & '01? Could this be part of the problem if they didn't swap everything properly? Car also seems to have some electrical issues....and stopped starting about 4 weeks ago. Puffs of white smoke from a box by the drivers side firewall.
I haven't had time to look into this until now....the car has just been sitting in my driveway.
Honestly, I'm not sure. There's a bunch of added electrical equipment under the hood and in the dash. Kind of hard to guess what it's all for. Is there an easy way to determine what ECU it is?
Sorry it took me so long to get back to you on this. Where is the location of the ECU so I can check it out and let you know? I'd buy a manual but it's hard to say which one I should get since it's supposedly an '01 GT engine. Maybe I should just spring for both.
The car won't start any more. I trys to turn over and stops (kind of like a dead battery but it's not). If you keep the key turned on, there's a ground that plugs into the EGR Feedback Pressure Sensor (up against the firewall) and it starts to puff smoke at the EGR (wire is smoking, not EGR). The wire is in bad shape, insulation is shredded. It disappears into a bundle of wires. Do you know what this is for or where it goes to? To find out, I'd have to cut the bundle open and follow it to destination and would like to avoid this if at all possible! The bundle splits to about 4 different directions so I can't just follow that. I'd mentioned that the wiring is a bit confusing from the engine swap they did. Nothing appears stock and there's a lot of spliced wires.... Fun, fun...
the ECU is located in the outboard right/passenger side cowl trim panel.....these "smoking" wires for the EGR could be a problem, you need to find out why they shorted as it does feed-back into the ECM.....also there should be a "loom tag" on the wire harness that id's the harness, hope they used the correct one as they are all different between years and if they used the wrong one, well that could be part of the problem too.....
