Sounds like it's low on fluid. If it was working good and this is a sudden change, check the fluid. The modulators on them are known to rupture the diaphragm and suck the fluid into the intake and burn it, so there won't be an obvious leak.

Yeah - I had hoped that would be the problem, but the transmission was full. Anyway, the trans is out, it has been rebuilt - now to get it back in. That should be soon - but first I'm going to fix a driveshaft safety loop. I have been having a little problem getting the right clip that holds the speedometer drive gear in place on the output shaft. Shop kept giving me the wrong part - but I believe we've got it worked out now and I can get the right clip in the morning. I thought while everything was apart I would get it fixed so the speedometer would read correctly.

Sounds like you will have a fresh trans now. Out of curiosity, did you check the fluid level with the engine running or turned off?

Running - with the engine and trans warm.

So I did get the right clip to hold the new plastic speedometer drive gear in place - so that all worked out. Next I installed a kit from B&M to recalibrate the governor. I wanted a higher RPM upshift. And I used a kit from TransGO to reprogram the valve body for a quicker + firmer shift. But the trans is still sitting in the floor - I've got to get to it.

Hey, you made progress, more than some do. You'll get it in...:headbang:

Well the transmission is back in. Don't know why but I had to re-adjust the shifter cable. Trans work good so I'll try and get out drive it some and enjoy it for a while. That will give me a chance to tune on the engine and try to get the best performance. Now on the getting the gears changed it the rear end.

Sorry I didn't get to bring my Chevelle to the SCR. I didn't have the new rear gears in, but then I wasn't feeling the best and didn't feel like I could load the car in the trailer and all anyway. Maybe next year - I hope.

The 3.73 gears are sit-up in the rear end now. My neighbor finally got to it for me. Now to pull the 3.08 rear end out and put the 3.73 in. Should have it all done in a few days. I know I'm slow at times - but I keep moving in the right direction.

Are all the bushings good in the rear suspension ? May as well address those, while it's out.
