How hard to rebuild?

If im going to rebuild my tranny in my shop class, taking it slow, with an instructor, how long/hard/$$$ will it be? My 1st-2nd shifts, well, they aren't there, i have to do it manually. Thinking its time for an overhaul. But then again it could be time for a trans command.

Guess this is a 2 in 1 post. Diagnosing the shifting trouble and rebuild.

Diagnosis: When cold, it shifts great, soft when not on it, hard when im on it, then when it gets warm, it wont shift from 1 to 2 without me stomping on it at 2500RPM. If i shift it with the stock, it will go right away, but usually when i put it back into D it locks up OD and lugs like ****. Trans was rebuilt ~35K Mi ago, under previous owner, full fluid, not burnt, added some lucas, no help. Unplugged batteries 1 hour, nothing.... Any advice?

Sounds like a bad torque converter to me.

You can get the rebuild kits from the vendors on here for a good price. You can also get triple disc billet tc from vendors on here.

If your going to rebuild it might as build it up while it is torn down.

Check the vendors on here. They know the cost of the parts.

What ? A bad converter will not cause shifting probs unless it is filling the VB full of metal. If this was the case there would still be probs when the traans was cold or hot. The valves would be stuck in the VB , cold or hot.

More likely since the trans was rebuilt someone left somthing a bit loose. Pressure is leaking some where after the fluid gets hot and thinner.

Thats my guess and I'm sticking to it.

I asked about the trans command quite a while back. Somebody more knowledgable said it isn't needed if you have good PCM programming.
