6 speed conversion
I have a 1994 convertible that I have been wanting to convert to a 6 speed.
I just came across a 1994 6 speed coupe for sale. The guy is asking $5400.00. It looks to be clean with 160,000 miles on it.
So I'm thinkin I could buy it for maybe $5000.00, switch transmissions, rear ends and whatever else and then sell the coupe for 4 to 5 thousand.
The question is , would it be worth the work?
Has anyone done this that could give me the heads up on what to expect?
Are there any wiring issues ?
With 160,000 miles on the transmission will it need to be rebuilt soon?
I apreciate any and all help,
Thanks,Rick

For a second I thought he wanted 5400 for the trans alone... 
5400 isn't bad at all for a clean coupe with 116K. Depends on the details though.
I'm not sure that the transmissions will match up between different motors. Does it have the same engine?
With the cars side by side, it shouldn't be too bad of a job if you have the right equipment You could probably just swap the motor and trans if its the same motor and not even disconnect the trans. Unless you have some money into the motor. That would change things.
Why don't you just drive the coupe?

This discussion pops up somewhat often, and people do switch to manual transmission, but with the price of C4s, it would be best to just outright buy a six-speed. 160,000 is a lot of miles and unless the car has been meticulously maintained you could be getting yourself into a lot of work.
Another option would be to post an offer for a swap for an equivalent car with a six speed for your automatic. Same result that will save you time (and make for more time behind the wheel of your car) and possibly money.

I also have put ground effects and a rear spoiler that I made myself that sorta looks like a 70's style camaro(lots of hours !!) and I'm liking the look of it mostly. Thats mostly why I want to keep this car and not sell it to get a 6 speed car.

Here's someone who has swapped a 700R4 for a ZF6.
http://members.cisdi.com/~anesthes/
Also, I know that the other forum members speak highly of the ZF6 Doc for his knowledge on all things ZF6:
http://www.zfdoc.com/index.htm
I know there are more threads on it though where people detail how they converted it but I don't have them off-hand. I hope this helps get you started.

My .02 worth
I bought a used T-56 I paid 1100.00 for it. It did not come with a LT-1 bellhousing. That was 175.00 I had the trans inspected "it was sold as ready to go" Yeah right i spent 1500.00 on the race rebuild. Now I have a sold trans. But for a little more I could have a brand new one from Tremec. If I had to do it over I would have bought a new Richmond. They bolt in place of the 4+3 and it is the only nonstock part to the build. At 3200.00 pull one out and put the other in. And Done! That is not to say I'm not happy it is just the long way around the mountain. Also the ZF is a very expensive trans to get rebuilt so I have been told.

This is a misconception, I don't know about the swap from an A4 to a zf6 in an LT1 equipped vette but there is cutting and patching involved on the tunnel on the swap on an l98 equipped vette, it is not a bolt in swap.

I did this years ago on my C4 before I sold it. The ZF6 swap was easy. Car was an '87 L98/A4
