ALL transmission codes on??? need help

[chvy=power]

thats weird...when mine was throwing those codes the trans wouldnt work..have you switched pcm's lately or anything??

[liftedboost]

no ,i havnt touched the pcm, this one is from allen ,had it on for id say 3 months or so. im starting to think its something with this pcm but honestly im lost and dont know what else to do.

[RedHeartbeat]

Try putting 12v to the pink trans power wire straight from the fuse block or battery with a fused link. Clear the codes and drive it around and see if the codes come back. The loss of 12v from the steering column would be an intermittent problem sometimes.

[chvy=power]

wouldn't loss of power to the trans from the ignition cause the trans to act up? he says the trans is working fine so im confused..

[RedHeartbeat]

Depends if the power loss is intermitant or a hard failure

Could be a bad pcm ground or broken ground wire. Tug on the grounds and see if the insulation stretches.

ill gve it another look at later tonight and see if that helps, if not ill just use a jumper wire and see if it does anything

[liftedboost]

well.....no point in testing anything lol, went to the store this morning on my way to work,it was driving fine ,shut it down,went inside ,came out and turned it on and hen i put it in D it felt like i had a 18 wheeler trailer hooked up to it, i think its stuck in 2nd or 3rd, pretty sure there is something wrong with the shift solinoid B , so im gonna try to reset the computer and see if it frees up so i can drive it to this a hole once again to fix it. geez man ,im doing the 80E conversion this is the most frustrated thing ive ever gone through, rebuilt 2 times, fixed 5 times within 4 months is ridiculous!

thats the same thing mine did...i still had second third and reverse tho. the trans is in limp mode. put it in second gear manually and it should pull off a little better... see if you have voltage to the trans on the pin E

[RUFFNECK]

Yeah limp mode. Be patient, Im sure its something very minor.

i reset the computer and now its back to driving right but the ck eng light is still on, i gotta work today so im gonna try to get some time tomorrow to take it to them.
