1995 Bonnie issues

I just replaced the crank position sensor on my car, what a pain. The car runs a little better, but it still misses when warm...it has new plugs and wires.
Does anyone understand this problem? When the car is warm and I step on the gas hard, the rpm goes up, but the tranny doesn't kick in until I release the gas pedal and then step on it again, plus it stumbles when accelerating, but it doesn't really do it when the engine is cool. At first I thought it might be the tranny slipping, but it accelerates well when it wants so I think it is something else as it is intermittent, possibly a communication error somewhere. I get no codes at all. Could it be the throttle position sensor?

The throttle position sensor could be the problem but you should get a computer code if that is the case. I would change the vacuum modulator on the transmission. I believe Fram has one for about $12 as it sounds like it is not engaging properly when you push the gas peddle. When you let off the gas peddle the engine will produce a large amount of vacuum and will cause the modulator to work. I would expect this will cure your problem. Also, check and make sure all you vacuum hoses are properly connected on the engine and at the transmission. Good Luck!

if no codes,probably data line shorted to voltage,my problem now.I think hvac programmer problem?.uart and
E and C data lines shorted to power.I am trying to resolve
problem now on shoestring budget.if you find fix,let me know. check voltage pin#9data DLC to #4 grnd DLC
