SOURCE: 97 silverado transmission problem

Theres a few actually in the the bottom of the trans.the most common problem with these trans and assuming its 4l60E is the pressure regulator switch.You have to take off the trans pan to get to it and its not that exspensive of a fix.You can do it your self in about 45min

SOURCE: i have a 94 silverado with a 4l60e trans. 1st and

how it sounds that the solenoids are going bad i would take it back to the shop were you had it rebuilt and have them redo it most shops give a one year warranty on the rebuilds if so they should be able to fix it for free.

Unless there's other circumstances the shop should have checked the codes first. From there they should have followed a basic diagnostic route such as making sure it has fluid pressure in all valve shift circuits and the correct pressure. But, it's most likely that you need a trans and a long test drive after doing the valves would have gave them a clear direction to go in if the problem is not interrmitant,

SOURCE: 04 Silverado no second gear

check color and smell of trans fluid, if not bright red and had a pugnant odor then the trans needs to come out and torn down, You can try a fuel filter that can cause a driveability problem

The tag is about the only way to tell. But if it is push button you should have a 246.

Stops shifting after i start driving

Allison transmissions are fairly reliable. don't really burn up unless you run them dry to many times. First you need to have the codes read. Even some engine codes will make transmission not run right. Then I would be checking the wires to the transmission for the ECM/TCM (Ohm test them). Along with the plugs for corrosion.

Clanking noise coming from Allison Transmission on a 2001 Chrevrolet Silverado 8.1 Liter engine

this does sound like theres a loose line tapping the engine/frame,during warm up the engine idles faster which could make it vibrate faster causing the the clanking or tapping noise,if this has started after trans fluid change,then check the lines running from the trani to radiator sometimes the service person might bang into something causing plastic clips that hold the lines to break,try getting under it and have someone start the truck and listen to see where it's coming from also hold the lines & see if the noise stops,the service guy could have unbolted something & never put the bolt back causing the clank ex.line may have a clip holding it thats bolted to the trani pan ?good luck

2001 chevy 2500 hd 4x2 allison trans seems to loose pressure after coming to a stop, have to rev engine for a few seconds before it pulls again, whats up with that? 88800 miles

I would start
by changing both trans filters and fluid, makesure you put dex VI in trans then if still having problems take to someone with a Tech 2 scanner and have them reset the trans adapts and try that, what it does is resets trans to factory (new) mode and then as you drive the truck it will adjust to your driving habits and shift points, but loosing pressure makes me think one of your filters is partially plugged...there is a spin on cartridge and the internal one in pan, change em both..good luck

2001 hd 8.1 with allison. Pulled my boat up a big hill, then the tranny warmed up just below the red line, pulled over and looked under, and it was leaking. Just dripping. Put a quart of fluid in it and...

There is no overflow on the Allison Trans, something happened when the trans got over heated, it is a good idea now to also get a trans flush as once you heat it up that bad it starts to break down the fluid.
