1500 and 1600 tranny the same?

Does anyone know if the transmission from a 1500 can be connected to a stroked 1600?

The 1500 and 1600 transmissions have different internals. Parts for the 1500 trans are pretty much no longer available.

Most notable difference is that the 1500 has a non-synchromesh 1st gear.

It can be connected if you mix the right parts, but why? The shifter comes out in a different location, the driveshaft is different. The lack of synchros and available spares makes it problematic.

I found a 1600 for sale which has a 1500 engine (has a knock). I have a great engine for the car, but was curious to see if I could use the transmission...

I'm guessing you could probably sell the 1500 engine and tranny for more than what a 4-speed will cost, and I've seen 4-speed transmissions as cheap as "free-to-whomever-wants-to-come-get-it".

Several people have commented that the tranny will fit in a large Rubbermaid container so you can ship it Greyhound (also cheap).

The lack of a 1600 tranny shouldn't stop you.

The 1500 engine has a knock - might serve someone well for spare engine parts...

Are you sure it's a 1500 transmission on that G15 engine? May be the stock 1600 unit since the car is an SPL311.

I thought of the same question this morning... if not, the 1600 transmission may still be around.

If it's an SPL311 and they didn't modify the transmission tunnel, I think it's a 1600 transmission. The 1500 has a large protrusion that the gear shift attaches to. Another way to tell for sure - get under the car and look tail end of the transmission. If the shifter is held on by a small cylinder that just barely juts out above and back of the transmission, it's a 1600. If not sure, take a picture while you're under there and post it.

I spoke to the owner of the car and the 1600 transmission is still in the car. When he did the swap for the 1500 he put a brand new clutch in. It was soon after that when the engine developed a knock. I'm still going to have the transmission taken apart and looked at to ensure the drivetrain is solid.
