RE: 700R4 question...
On my '87 if I'm running in OD, which I am almost always, it will shift down to 3(drive) or lower depending on the speed I am traveling at the time I stomp the gas. Lets say at 40 you stomp the gass it will drop to 3rd or 2nd as needed or if at 60 you step on it it will drop to 3rd. The tranny will shift to different gears as needed depending on speed and load. hope this helps, Cheers

I adjusted my TV cable a few minutes ago. I just had new plugs/wires installed. I was driving today and thought it was shifting funny. Before the new plugs and wires the timing wqas set to 0*BTDC... believe it or not. The mechanic told me it was retarded that much. They set it to 6*BTDC (factory specs). Hoping the adjustment will help. Maybe the shifts are that smooth? I have 88k miles, assuming the tranny is original. Before the plugs/wire swap the1-2 shift point put me in the back of the seat. It was real hard. Now the shifting seems like it is very smooth and close together. [sm=helpout.gif]

I did it in my '87. For awhile (I hardly ever drove it), it strung out the shift point, and shifted hard. Then it was back to normal.

RE: 700R4 question...
Disconnecting TPS with battery connected doesn't cause a relearn because you haven't changed anything. To relearn throttle position, you have to disconnect battery for 5 minutes in order to let the capacitors in the ECM to bleed down, then you lose throttle position memory. On an 89 model with a 700R trans, shift points are not controlled by ECM, but by the TV cable from your throttle.
