I've just started the engine after rebuild and now the trans won't shift into gear. No reverse, no forward gears.
When i first started, trans was about 2 quarts low on fluid, but i added fluid with engine running, and it's now on normal level. I went through all gears, but nothing.
Trans was out of the car for 9 months, but it ran normally when i removed it.
Any idea what could be wrong?
Could routing of cooler lines be wrong and cause this? I don't think so.

Fluid level drops a few milimeters when the engine is started. The linkage is OK, I checked it because I installed new cable bracket.
My trans is converted to full manual operation with TransGo shift kit.
Converter is properly bolted.

One more thing. When my engine broke, I had tu pull the car home.
I didn't tow it, since it was only a mile or mile and a hlaf from my home.
Could've that caused the problems?

Any idea is appreciated!

Are you sure the converter is bolted? Was the converter installed dry? I always drain and refill the converter when I do a swap...

Yes, the converter is bolted.

Converter wasn't dry. I never took it out of the trans when I removed it from the engine.

I forgot to mention that I've also installed the new trans pan. When I've put engine/trans back into the car, I've installed the new, aluminum oil pan. when the pan was down, I have also installed the new filter. Than I've added the fluid to the max, and started the engine. As the engine ran, I had to add about 2 quarts more to get it back to normal level.

Yes.

Could somebody check where is fluid level on dipstick with engine off?Pete suggested (on another forum) that it might be a pump problem, and I think that he might be right.

The more I think about it, the more I believe that something broke in the trans in the same time when I blew my engine. Maybe even the trans went first and that was why engine overreved!?

Sorry to hear about the problem.
After the trans has been filled to the full line (hot) and the car the has been shut off the fluid on mine is about 1" or so above the full line.
However, on new set-ups I just put fluid to the full line (cold) and fill to were it is needed after the car has been started and warmed up.

Thanks Mick!

I guess that this will put a delay on my logs. I hope that this won't be a problem for you?

OK, here is an update, finally.

I've tried what Pete suggested on another forum and it looks like ther might be a problem with the pump. As soon as I start the engine, fluid starts to flow, but it flows for a very short period of time and than it stops. (Take a look at the video).
Fluid level was in the middle between min and max when I tried this.

Opinions? Pete?

It looks that my luck might be getting better. I've pulled the trans pan
and found a broken filter neck. I really don't know how it happened but
it looks like because of this, pump was pulling air and maybe some fluid,
but definatelly not enough.

I only hope that this didn't cause any other problems. I'll know soon.

Also, over the time I did some research regarding my 3-4 upshift problems
and I've found that there are some modifications that can be done to
improve 3-4 shifts, so while I have the pan down, I'll try to make them.
