Default HELP!! Need to remove tranny sensor! Car fights its self!

I just did a tranny swap on my 92 bonnie that I just got for nothing. The only problem that I am having is that the tranny fluid level sensor is a little different. The connector is shaped differently on the inside. How can I remove the sensor to swap it with the original?

I believe the trans is from a 95. It does say 4t60-e. I just tried driving it, and it moves in reverse just great! The only problem is forward drive. It feels like there is a break grabbing in drive? I got into WOT and it will not rev over 3000. Feels like a break torque...Any ideas?

That'* odd. I always thought the 92-96 Trannies were identical. We may need some pinouts of the 92 and 95 connectors from factory service manuals.

Can you find a manufacturers date on the Trans you're installing? I'm hitting the books. If I find anything revealing, I'll post it. If I don't post......GOOD LUCK!

Stay tuned....within the hour. I'm working on something VERY revealing here........DON'T GO AWAY!

Don, Hit the schematics in your Chilton'*. Compare the years. You'll see what I found

1992 used a 6-wire connector for the Trans. Pins a, b, c, d, e, f.

ALL THE INFO I HAVE ON IT:

Pin A- purple wire, to ABS brake switch and pin A5 of the PCM black connector.
Pin B- Blue wire, to pin C15 of PCM orance connector.
Pin C- Black wire to pin D15 of PCM black connector.
Pin D- Tan/Blk wire to C6 or orange PCM connector
Pin E- Brown wire to Fuse #16 (check this fuse).
Pin F- Lt Green wire to D16 of orange PCM connector.

1993 is identical to 1992.

1994 and 1995 have a 6-wire connector also, I don't have the pinouts, but I do have this:

Tan/black to E12 of PCM.
Lt Green to E14 of PCM.
Yellow Black? to E15 of PCM
Dark Blue to A13 of PCM
Yellow/Black to F14 of PCM
Brown wire to Brake switch and fuse 5C (hot at start/run).

Note that some of the wire colors changed, as well as PCM pinouts, as 1994 and 1995 were hybrids of sorts. There is also a single wire (another plug?) that goes to the EGR and IAT sensors. Also connects to C6 of the PCM.

Now for 96 and 97 (which oddly bridge the transition to the 4T65E which appeared in 97), the Transaxle connector has 7 pins as well, plus that extra wire (another connector?) going to the IAT, fuel press sensor, map sensor, ECT sensor, tps, etc.

98 and 99 go goofy. a 12-wire connector, plus the extra wire, going to the PCM and fuel pressure sensor.

All I can tell you is that you SHOULD see different wire colors that match what I wrote above if you cut into the harnesses of each trans. Hopefully you still have the old one for comparison. You may also need to shoot the pinouts on each trans to see if anything appears to have changed. I hope some of this helps you.

We need the Rat in here. I don't have transaxle part numbers. Were there any differences between 92 and 95?

I hope the new tranny is compatible with your computer. The wiring may be the challenge.

And mine (93 SSEi):



But my schematic only shows 6 of the 7 being used for 93, and all 7 being used on a 95. Check your Chilton'*.
