Hi, I have most of the parts to install a 700R4 to replace
3 speed manual. Are there any mechanics around Green Lake Wi that can do it?
thanks!!

Are you aware that this trans swap will require the engine mounts to be changed to the side mount system and having a trans crossmember installed (or maybe you already have it that way)?

You have chosen what is the most difficult transmission to swap effectively of all the ones that will bolt up to the V8 engine. The geometry of the throttle cable linkage that controls shift points and pressures leaves absolutely no room for error. Getting the engine/trans assembly to bolt together isn't difficult at all. Getting the trans to shift properly and not destroy itself is extremely difficult. A turbo 400 or even a 350 would be a much better choice. Good luck!

I second this on the TV cable. They really are very finicky. I would recommend having a *good* shop set that up for you. One with a warranty.

I have heard good things about BTO's kits (pick the one for your carb [bowtieoverdrives.com]), but I ended up deciding to put an 4L60e in my project(s) instead.

Good luck!

Have you thought about a T-10 or a close ratio 3 speed. I won a bunch of of drag races with both types of Borg Warner's. Had a few aluminum case 4 speeds but, I'm a little set in my ways. I prefer cast iron, hey it's weight down low on my 57-150 and it helps the front from bouncing up a little too much. Pending which rear end I'm running I get very good performance on the close ratio 3 speed. Either one will fit right in nicely with no modifications. Listen to Jerry he is a pro. No brag, just fact. doc

While we are on the subject; What is the big deal about Tremmic (spelling), 5 speed? My 57-150 has the close ratio and I can get a Tremmic for cheep from a kid that has to get some money now. Looks new. doc

Have you considered using a 350-C transmission, the one with a lockup clutch in the torque converter? It gives a 10% increase in driveshaft speed when the TCC locks in after going through the normal 3 speed shift pattern with 3rd. gear being direct drive. Getting 10% more driveline speed (or 10% less RPM) without going through an extra set of planetary gears is probably better efficiency-wise than having an OD.
