i know the forward is the same size as the rest. but on the 1-2 piston there is a small and a large hole piston. i have a 1994 ta with the original trans and would like to get new pistons for it. would mine be the large hole or small. or is there like a year break when they stoped using one and started using the other. any help would be great.

should i just get the replacement pistons or should i pick up some pinless ones. would upgrade to the pinless even be worth it.

Aluminum replacement pistons would serve you well. Pinless pistons work just fine in high horsepower apps, but I think they can be overkill in a street application personally.

Wouldn't hurt a thing to run either setup... it boils down to personal preference.

thanks for the help it was what i was needing to know.

The 1994 would have the small hole. There is an aftermarket aluminum piston with more pin to surface area, for better wear, and there is a "hardened" (RC52) small diameter pin available for these.

I say for 1994 it would have a large pin.

It should be a large pin, but, I've seen both. We carry all 3 styles in stock. A shop near you should carry them as well as new pins.

I didn't expect this, I'd say thats the normal course of action right there.
