hey I was having these problems

I have also had my trans light come on, and usually my reduced power light when I make a sharp right turn.
I tried checking the engine harness, and I got the reduced power light to come on, AND I got the motor to stall. So I opened it up and went thru the wires one by one.
once I got most of the wires seperated, I couldnt get the car to stall anymore. took the car for a test drive and drove it hard and couldn't get any faults. so I started to tape up the wires again, I did maybe half the length of what I cut open - checked the motor, everything was fine - no faults. I taped up the rest and I barely touched the harness and the motor stalled. Needless to say I took the tape off the second half for the time being. to continue testing tomorrow.
With that said - I would try your harness like the others suggested.
just start off near the 'brain' where the harness plugs in (driverside fender - metal thing with two main wire plugs about 4-5" each). with your motor on start squeezing the conduit that the wires are in. I found that putting pressure on the conduit top and bottom and then left to right worked out better than trying to squeeze the conduit as a whole. eventually you will hit a point where you apply pressure and the motor will almost stall or complete stall on you. Again, I'm only at the point where I have seperated the wires and have pulled maybe 20 wires individually - included one of the red/white ones mentioned in FAQ61. I couldnt get the car to stall so I taped them back up yaddi yaddi yadda mentioned above.
sound like you and I might have the same issue! I too feel like its a tranny issue - I mean the trans light comes on! but after checking the harness and seperating the wires giving them some 'breathing room', my truck drove like a dream!
I will keep you updated with my progess if you like
