Just started up my freshly rebuilt blown small block Chevy (roller cam) and TH350 today but I did something really stupid...I didn't realize it was in low gear when I did. At first I didn't notice anything but the first time I gave it a little gas it moved forward to my surprise. I guess the converter had filled up by that point. I immediately stopped the engine and then realized what I had done. I understand the correct method is to slowly engage each gear so the transmission fills properly. So is this a big deal...have I potentially burned up some clutches. The transmission is a high performance rebuild I did myself with a pretty loose 10 inch converter.

I doubt you did any damage. Usually when a trans is damaged from low fluid it is because it has been driven. Top it off to the required level and give it a drive, you probably didn't hurt anything. Lucky you didn't stab the throttle though .

Did you fill the convertor with trans fluid before installing it ?

I would agree with 302/Z28. You need slippage and heat to do severe damage, and being that you just started it, you should be OK. Thankfully you did not get hurt, or hurt anyone else when the car moved. Hope everything works out well.

Thanks all, I think I'll be ok then. Just lucky I didn't hurt somebody.

I installed a TCI convertor and did not pre-fill it, although the trans was full of fluid it soon turned the convertor to trash.
Here is an excerpt from the B/M installation sheet.

I did fill the converter although I don't think I filled it to capacity. I guess as long as there is some in there then its enough to protect it on start up.
