Default How to modify a T56 for a C3

Hi

A friend got a T56 ( was ment for a C4 ? ) and likes to install it into his C3.
He would like to know what he needs to change in order to have the mechanical speedo output.

I bought a GM T56 Viper tranny from D&D 1 year ago and this had a differenmt tail housing with this mechanical speedo output that just accepted the ordinary M21 speedo gears.

Any ideas or suggestions ?

Here some pics of his T56.






Thanks a lot. Günther

Seeing as how thats a Borg Warner T56, I'm guessing that it was from an LT1 F-Body. If so, you'll need to customize your console, speedo, and bang on your trans tunnel a bit. The yoke is the same, the trans will sit right on top of the x memeber with a GM trans mount and obviously you need to shorten the drive shaft. You need an LT1 clutch and centerforce flywheel 700107. For more info do a search, someone new asks this question everyday it seems like.

Hi

Yes, I know.
The question is only valid for the mechanical speedo output.
He likes to know if this tranny tail housing can be modified to accept the mechanical speedo cable somehow.

Thanks. Günther
