Default 4L65-E transaxle dimensions?

Hi all,

I am planning to use a 4L65E in a custom car build, specifically one pulled from a 2005-2007(?) C6 Corvette with the A4 transaxle setup. This will be a scratch-built vehicle (Google "Lazareth Wazuma" if you'd like to see the approximate form) and I'm trying to determine some of the basic dimensions. Does anyone know of a source somewhere online with detailed dimensions of the 4L65E that is specific to the Corvette? Specifically I'm looking for:
  • What is the length of the main case alone? (Is this identical across cars and years after the 4L60E went to a separate bellhousing?)
  • What is the distance from the surface where the differential mates to the driveshaft centerline? (Or what is the overall length from torque tube to driveshaft centerline of the transaxle, and overall length to the rear of the diff?)

If someone would be willing to do some quick tape-measure work for me under their car that'd be awesome. I've done lots of searching here and on Google but the only measurements I could find were for other applications and differences between years, and nobody is swapping a Corvette-sourced 4L65E into their mid-trans, RWD car for obvious reasons.

Thanks in advance for any help!

The 4 spd Automatic was only used in one year of the C6, 2005.

You might try the C5 forum, all the C5 Automatic transmissons were 4 spds.

BTW; Its not a transaxle, the differential and transmission are separate housings with different fluids.

Oh hell, looks like I screwed myself here a bit. Bought one from an '07 and thought I was getting a 4-speed. Turns out it is in fact a 6L80, and unlike the 4-speed you: A) can't get stand-alone controllers for it and B) can't interchange bellhousings...

Anybody want a nice '07 6L80E with only 26k miles with differential and TC included on the cheap? This might find its way to the FS section in the near future...

Anyway the questions here remain valid. Asking in the C5 section also, thanks for the info!

Something like this might be right up your alley as far as standalone control.
