Bolting an 88 tranny to an 84 model?

[PeanutinCA]

Can this be done? I know the issues with the mechanism to drive the speedo. But, does the rest of the 88 unit bolt straight to an 84 chassis (mechanics)? Jason spoke to a shop about fitting the 88 tranny we have and he thought he recalled they two would not mate up? Unless he is just thinking of the speedo compatibility issue? Both 944's, not 924S.

 

Thanks,

Dylan.

Speedo is not an issue in an 84 since the early cars have a speedo pick-up in the left front hub. Putting an early box in to late car means no speedo.

 

THe only thing different about the 88 box is the mouting. Early cars use two mounts configured like ears off the box. Late cars use one center mount. Try to look on ebay for pics. I know there is a late one on there that shows that single mount.

 

Anyway that is the only issue. Not sure but I believe you can retro fit the early mount on the late tranny for use in the early car.

yeah, Dilly.

You can interchange the tranny mounts. All the points are there on both the early and late styles.

The early cars have 2 "ears " that are bolted to the diff plate on one side(3 bolts are slightly longer than the other 7!) and to the case on the other side.

The late trannys have their mount on the top center and it consists of 2 long 13mm? skinny bolts.

Just keep whatever came with your car and you'll be fine.

Anybody want an 88 tranny, for the right price? We could even do a try before you buy, I'm sure I can trust you guys. It's in the 88 I have, Jason isn't going to bother with it. Other influences may hinder his ability to make events?

 

So it's up for grabs. Only issue, you have to come unbolt it. Sorry, but my neck will not accomodate dropping a tranny.

 

Contact me if your interested?
