The block on the 2.6 engine was the same for both the auto and the manual for the 87 and 88's. The 89 2.6 only have a stick but again its the same block.

In the 86 and older 2.6 engines the auto gets a differant block since its mated to a baby 904 tranny. Thats the one of a kind block that IMHO is generly good for scrap.

The 904 tranny was only a 3 speed. <img src="/forums/images/graemlins/rodent.gif" alt="" />

The 4 speed auto is basicly the same on the V6 and the 2.6 engines. The later V6 units get a lock up converter that has a better torque multiplication ratio. That tranny behind a turbo 4 is a great setup.

As far as the bellhousings, they only swap on the 4 speed auto tranny.

Apparently the converter thats on the 4 cyl is the runt of the litter and to be avoided is you run tall tires. The V6 converter seems to work a lot better, with the lockup version being the best.
