Is the problem a bad trans in the 99? What car is it for?
Guessing he wants a manual instead of the Auto?
I would imagine Quicktime would have a LS to LT-T56
If you are wanting to put that LT1 T56 behinds an LS engine just change out the front plate and input shaft, that's the only difference. Just make sure you get the input with the same amount of teeth.
No, I haven't driven it much (expired tags) but it seems to shift fine, but it's an auto. I'd rather keep the POS manual.
But I also realized the other day that the 4l60 would probably fit easily in the POS if I didn't want to wait for a T56.
I might just keep the 4l60 for the 57,whenever that might be.
As for converting the Lt1 T56 to an ls, that's really the only option I see explained on forums.
Pro of converting: then I know it fits.
Con(s) cost of bellhousing, front plate, input shaft. Also then I might not be able to use my current hydro clutch linkage, and have to buy another setup specific to LS applications.
Sounds like I might be in around $500-1000 for these pieces.
But what I come back to is, if my current T56 is connected to an old SBC, and older SBC transmissions seem well regarded to fit behind LS's, why can't I put these two together?
As for clutch, I have a McLeod hydro T.O. That pushes against a standard old school Chevy pressure plate and disc. These things were said not to fit either, but I've put tens of thousands of miles on this setup.
The only hiccup I can imagine (besides no one else recommending this) is the starter not fitting. If I can figure that, I'll just mock it up and see if I can make it fit, or if grinding is necessary.
