Hi all
Can anyone tell me if the gearbox and diff in the 1800 sierra are the same as the 2.0lt
many thanks

Depends on engine. If the 2.0 is a dohc then no

Most 1.8 CVH Sierras have Type 9 & 3.62 diff, but they do vary from car to car.

My 1.8CVH Sierra donor came with a Type 9 box & a 3.92 diff, it was an estate version so not sure if that had anything to do with the diff ratio .

cheers

My original donor was Sierra saffire and also came with 1.8CVH and Type 9 and 3.92 diff

As ^^^^

Gearbox from 1.8 cvh is the same as a 1.6/2.0 pinto with regards to the diff they do vary slightly best thing to do is check the metal tag it will have the ratio stamped on it
Hope this helps
