I had a fresh rebuilt TH350 I dropped the torque converter in, bolted everything to the engine, filled it full of oil, and then fired it up. Nothing would happen when you put it in gear! We fiddled with this for a while decided to pull the transmission. Upon inspection after disassembly the 2 keyways that drives the oil pump inside the tranny are sheared off. I assumed something locked up in the tranny. I took the transmission to the guy who built it. He said upon inserting the torque converter I pushed the plate that held the keyways in too far and caused them to shear off. Now this just doesn't sound logical to me. I have no clue about tranny's so any help would be great. I'm wonderin if he just doesn't want to pay for this thing or what! so let me know.

unless you drove it in with a 9lbs sledge it would be pretty hard to shear them off one thing that could have happened is if your converter wasn't long enough to hit all 3 then the force may have sheared the first ones off

Probably what you did was not engage the converter into the pump drive tangs and bolted the tranny up tight,shearing the tangs off in the pump.Always turn the pump while installing untill your fingers can no longer fit between the converter and pump.

Yes I bolted the tranny up tight, but then i had to slide the torque converter out just a little to bolt it to the flywheel. So no i did not force the converter on with the flywheel. I think thats what you were saying rico. Is 50 bucks a reasonable price to fix that problem. it just sheared the gear that drives the oil pump.

Ok,that seems fair,but why did this happen?I've never seen one do that on it's own.I'd look more closely at the trans,you may be doing this again if you don't find the problem.

Can you push the tang in by just dropping the torque converter in on it and pushing and turning slightly? The tranny guy said it was broke befor we ever started the motor. I didn't buy that part. Thats what i'm concerned about.

Are you running a rear motor mount of any sorts????? If so you will need to put spacers inbetween the convert and flywheel so you won't have to pull the converter out to bolt it up.

What are you meaning about a rear motor mount? It looks to me like i need a spacer also, but the transmission guy says no spacer! I hope it breaks again so he will pay for both breaks! hehe Only teasing!

Do you have a Mid plate on your car. that is what i am refering to as in a rear motor mount.

The tangs are cast steel and are part of the pump gear,they are tough and usually don't break very easy,installing the converter shouldn't break them unless you use a sledgehammer.Seems like someone has messed this trans up before you got it.

rico08 i wish you could talk to the guy that put this transmission together. HE is dead set in his mind that when i put the transmission together with the engine that I squeezed the torque converter in also. I told him repeatedly that i had to slide the torque converter out to get it to bolt up. aftre the transmission housing was bolted up.

nut3D no midplate on my car just 2 motor mounts and a tranny mount.

I feel for you but in racing the warranty usually expires when you start it up.You are at his mercy,i was told a long time ago that this is racing,nothing is easy,it never just bolts up,and you have to fabricate everything,so it's normal.

Looks to me like the pump was not assembled properly,providing you had fluid in it prior to startup.In this case 5 quarts.
