318 Transmissions

[Ronw435]

Does anyone know if all the 318 chevy 3 speed transmissions have the same output shaft?

Thanks
Ron

are you refering to splines or length? some {trucks} have short tailshafts,{cars} long tail shafts

Yes CV65 I was talking about the splines.

I learned the hard way that they don't all have the same diameter bearing retainer on the front. The 318 in my truck crapped out, and I bought what I thought was an identical one at a swap meet. Apparently the one I bought was out of a passenger car. The bearing retainer diameter was smaller on the 318 I bought, so it didn't fit tightly into the hole in the bellhousing as it should. It was at least 1/4" smaller.

I read where you can take the one off your transmission and use it on the other one, is that not correct?

I believe so, yes.

Does anyone know what you can use as a intermediate shaft for the cluster gear to be able to install new bearings? It has to be shorter than the original one I believe or you cannot get the cluster gear in.

Thanks
