ok guys,
I built my engine and put the flywheel (automatic) on backwards I think. I had the torque converter go into the indents for the bolt holes on the flywheel. it worked when I drove it in and out of the garage and up on the trailer, but when I tried to get on it, it quit. Am I stupid and put the flywheel on backwards and ruin a tranny and torque convertor? I haven't torn it apart yet since I just moved, but I know how I put the dumb thingy on.

i have seen that done before, and yes, you probably have broken your front pump gears. because the clearance is not right when you do that and under stress the torq convertor hub disengages from the drive tabs on the fragile cast iron pump gears, and they get broken or at least damaged.

Yeah that's what I was afraid of. Is it hard to change the pump? I got another tranny, but the case is broke.

I don't know, didn't check it, but I'd assume not. The pump is definately not working though, it's like its in neutral no matter what gear. Park works too and I know the valve body is shifting, I checked it too.

It's a chevy TH-350. Can I just swap the whole pump? Isn't it easier?

you can swap pumps if the 2 trans are similiar years, by that i mean, some newer 350s had a bearing on the backside and the older ones had a bronze washer, if you change the pump just leave the same washer\bearing on it, make sure you replace the pump gasket and o-ring and front seal.
hope this helps ya.......ford5

Hey Racenmotorsports. I had the same problem when I ran a straight input shaft for my T-350. I clipped off the corner of the pump gear. I took he pump out and then separated the pump halves. Took the input gear and flipped it over so the tangs were out way from the back of the pump. That way I knew they would engage at the backside of the slots in the drive shaft. Discussed it with TCI when I visited them and their only concern was making sure nothing bound up. On your torque converter, you might want to lengthen you slots just to give you a bit more clearance for "just in case".
