I am building a " REAR MID ENGINE "car (RWD). The engine is "LS 3" and I don't use any turbo setup with it (stock from).
Now my question is " Which transmission/ transaxle is best for the build?????? ""
Requirements:
1.budget $500-2,500.
2.6 speed transmission.
3. Must Paddle shifter.

 

probably something from a porsche or audi

 

Most of the people here are not going to have much experience with a Trans-Axle...

The closest thing that the Members here would be familiar with, is The "Corvette Version" of the 6L80E/ 6L90E that directly connects to the Differential.

You should probably look at some of the European Trans-Axles.

 

Brother i want this type of build

 

I think some 4T80Es bolted up to a LS style block. May have to have an adapter made.

 

4t80e can bolt up to a LS4 style block

but that is transverse mounting. Not longitudinal

There is a pretty in depth porsche conversion on this forum in the "conversions and hybrids" section. maybe give that a look

 

I did not bring up the 4T80E because it is not a 6-Speed, nor Longitudinal...

However the GM Racing Division has Front Wheel Drive cars running Twin-Screw LS4 Engines with the 4T80E in the 1,500 HP range.
The 4T80E is stout Stock, and can take a real beating modified!
