gearbox query

[rumble]

putting in a 2nd hand engine (with gearbox) into a sierra (1 litre). I've noticed the gearbox is different-is this a 5 speed or what as the engine is the same as whats come out. I've never worked on one before so some advice would be welcome.

is there a pic missing?

With the 1.3's there is a 5spd

with the 1.0s there is both.

cheers

There is two different 4sp gearboxes in the Sierra 1.0. Up to 11/84 and 11/84 on. The 11/84+ is longer than the earlier one and shares a lot of the same internals as the 1.3.

[rumble]

Yes it is longer than the 4 speed but is bigger overall. I will need to get a shorter driveshaft to the transfer box.

Have you fitted the gearbox yet?

[rumble]

not yet-the drive shaft would have to be shortened and there is no output seal. Thinking about just putting back the 4 speed for now so it can get it running

[Santos]

so it's the 11/84 gearbox that can be converted to 5 speed using 1.3l internals?

Rumble, the reason for asking if you had fitted the gearbox was in respect that I don't beleive it will be a straight bolt in. The cross member where the gearbox mounts to is in a different position the between the models with the different gearboxes. Therefore the cross member in pre 11/84 1.0l Sierras sits a little forward of the later model. I remember seeing the 1.0l 5 speed conversion being done to a pre 11/84 model and it was a bitch to do because of that cross member. I think you will need to do more than just shortening the jackshaft to fit the gearbox.

Santos, the gearbox out of the Series 3/4/5 (11/84-86 w/plastic dash similar to 1.3l) and Maruti is the gearbox that can take the 1.3l 5sp gearing.

looks like i'll put the engine in with the 4 speed -your right -the cross member would need to be moved back & possibly some mods to the tunnel to line up the gearstick as well as the driveshaft
