It'll fit, the Vette auto Torque converter bellhousing is much more compact and is about same size as the 6 speed bellhousing in that area anyway.

This LS 5-speed is up for sale. Gotta make room for my next project with Dins. PM with offers.

Maybe warrants it's own FS thread.

The T handle gets replaced by a big black box. Unless you can hide it somewhere other than where the T handle used to be, it will be more of an eyesore that the original shifter. I understand the novelty of a paddle shifter but unless you planning on using the shifter all the time, I guarantee you it will get old, fast, there is little point doing it. Unless its a DSG transmission, paddle shifters have no real purpose in a car.

I agree with the comment regarding paddle shifters. My MB SL55 AMG has the three options - standard Automatic, tiptronic and or paddle shifter. I used the tiptronic for the two days I drove on the track, use the paddles about once a month, just to show someone what they are and how they function. 99+% of the miles are in good old quick shifting automatic (I DO wish I had this 5 speed transmission with a low numerical final drive - less than 2.2 - in my GTS. A 6 speed would be even better!).

Not sure what you mean by 'big black box'. The digital control module present is no bigger than the shifter plate. With a little customization, a plate can be fabbed to conform around the digital shifter and mount it flush with the plate itself. I think it would look rather unsual, but intriguing at the same time.

With regards to choosing the 4L60E with paddle shift over the 6L80, I would prefer to go that route since most aftermarket TCUs on the market are perfected with the C5 Auto. A 4L60E with a 3.73 or 3.90 would be a fun little car to drive around town, but possibly a gas mileage nightmare at 65 mph.




By the way, can anyone answer this? Why does the C5 Corvette owners manual state the Final Drive Ratio as 1.91, but the axle ratio as 3.42 for the automatic, that is if the car has the 3.42 option?

How would that relate to the 928? The final drive ratio is 2.20 on the '87-'88 S4.

That looks like it belongs in a bus.

Look at the box that has the shifter cable coming out of it. It has to have a mechanical shifting mechanism in there that is probably actuated by an electric motor/servo. The range of motion that the sable needs to move is probably about the same as what the T handle has so, does the real estate required to move the shifter cable. Unless you hide that box somewhere under the car or under something else, that box installed in the same spot as the T handle, will stick out quiet a bit.

I'm going with a 4 speed auto with a 2.72 that I already have on hand for my next 928 hybrid. Now that the clutch is broke in, I start in 2nd gear and go straight to 4th. Sips gas as a DD if I can keep my foot out of it.

The box is not that large. See the video. PCS may have also created a shorter cable due for purchase too. I bet you that sucker would fit either under an aftermarket seat or if you have a rear seat delete, under the frame of it. If people can shove a subwoofer and amp where the seats are, why the hell wouldn't the box fit there too?

As far as I know the 3.42 was the final drive for the M6/M12 (Z06) cars, and not the autos. The final drive for the automatic was generally a 2.73 with another optional ratio I believe (3.15?). I'm pretty sure the 1.91 is the last ratio in the TRANS, not the rear.

Just got a little extra info. Turns out I was right!

Hey Jon, Have not heard from you in a bit. C5 Z06 is what I am running in JP. Really cool mechanical whine when running through the gears. Reminds me of the ol M22 rock crushers. T

I see autos on ebay with 3.42 rears. Maybe manual diffs dropped into 4L60Es?
