Default Tranny help!

my tranny seems to be one of the good ones...

it goes into drive and revirse fine but when ever i give it more then half throttle it doesnt want to go. if i put the gas all the way down it feels like it slips into neutral and very slowly moves until i hold the gas down for a few seconds until it grabs but it stll wont gear down. when i does shift it doenst shift hard and the trans fluid is still red and doesnt smell burnt. any one have or no of any issues like this? what would thecosts be for the fix (around)?

Considering all the problems you're having in your other topic:

2 blinks pause 1 blink (3rd code)
4 blinks pause 2 blinks (4th code)
4 blinks pause 4 blinks (5th code)
5 blinks pause 8 blinks (6th code)
1 blink pause 2 blinks (end to codes)


It then went through these over and over again... what are these codes?
17 spark reference circuit. Crank sensor, Cam sensor, or ICM are the likely culprits other than wiring.

18 Cam/Crank error. Backing up the code 17. Looking more like a sensor now.

21 Throttle position sensor. Is it installed correctly? It'* thinking it'* at wide open throttle if the voltage is high. You have a sensor or wiring problem.

42 Ignition Control Circuit. Your PCM cannot take over control of the timing and fuel, so the ICM has to run in Module Mode. You may have a bad Ignition Control Module or a faulty connection or shorted wire.

44 Oxygen sensor. It'* either bad, or you have a wiring problem with it.

58 is a known bug in the 92 PCM. Ignore it.

At this point I'd start suspecting a possible bad PCM, however I think the first thing to do is change the ICM. It'* not handing off control to the PCM for timing and fuel. It MAY also be causing the other two codes that point to cam/crank sensors.

If that fixes those codes and the car starts, replace your TPS and O2.
I'd try to get the car started and these other issues fixed first. It might not be your trans at all.
