Missed that oops... 24-2500 will be fine for me, converting truck to vvt as well, and i dont expect it to be but maybe 350-375hp to wheels more would be cool but not lokking for much more....

 

I have just ordered all of the parts that Sonnax makes for these transmissions, my 14 has only 7000 miles on it but I cannot stand how it shifts and will install the Zl1-Cts-v converter while its out. The leak down issues that they have are mixed with poor machining and the really soft aluminium that the valve bodies are made from not to mention they are made by AISIN !! I also will be tig welding the drums too.

ive been looking at caprice ppv converters.... trying to find stall on stock 6l80 converters

 

Has anyone converted a 2wd 6l80 to 4wd??

 

The ZL-1 or CTS-V converter is around a 2000 RPM in a truck from what I have been researching. and they are $300 bucks new. I think the only difference between a 2 and 4wd trans is the tail shaft housing, the output shaft seems to be the same length.

Im wondering about the plugs/holes in rear of the case.... There are 3 different 2wd output shafts and one 4wd.... The 2wd shafts are dependent on whether it has a slip yoke, flange or a vette transaxle setup... I have also seen where the output shaft seal and retainer are different, between 2 and 4wd... Saw a thread on one of the jeep forums(i thinknit was) converting a 2wd to 4wd and they plugged the holes in back of the case.... Cant see gm designing different case for 2/4wd that cant be reverted.....

 

They are like freeze plugs.... you can take them out or install them.

Ok does the 4wd need them open or closed off.... Assuming the seal being there and nothing but a solid splined coupling to the transfer doesnt need fluid in theadaptor housing....

 

That's a six bolt converter. You'll probably need to mill down the extra bosses. I had it done on mine. BTW, headers/tune that setup stalled to 1,800.

 

The cts-v have 6l90s and then the vette is ....well, just a different world....
