Tried searching but couldn't find anything. What all is needed to convert from a 5 speed in '93 'maro to a 6 speed. Probably not much besides maybe a shorter driveshaft? Also what would be better both pricewise and performance an M6 or a T56. Is it even worth the swap? Keep in mind its for a car with 4.11's so maybe it would be worth it just in gas saved .Thanks

 

its not worth it. im assuming your talking about a V6 since it has a 5 speed. the V6 doesn't make enough torque to require the six speed. all you'll be doing is using more power to turn the heavier tranny parts and more power to haul around the heavier tranny itself. plus i dont think you can bolt an LT1/LS1 6-speed to a 3.4 liter motor. BTW: the f-body M6 IS a T56.

 

the only 4th gens that came with 5 speeds would be V6s. A t56 from a V8 while it may bolt up (I don't know) would not be a wise idea, as the v6 doesn't have enough torque to make 6'th gear even remotely usable.

 

I was talking about a z28. I was under the impression that in 1993 a 6 speed was rare. I guess I assumed this meant a 6 speed was rare compared to a 5 speed when it really meant a 6 speed was rare compared to an automatic. So if thats the case that means all manuals in 1993 were 6 speeds? Thanks alot

 

As you can see in my sig im "one of those auto guys"

 

there were 2 different t56's available in 93. One was the M28 the other the M29, with different 1st gears, and I believe one has a higher torque rating

 

yeh I remember reading something about that in the list of differences between the 93 and other years on a forum somewhere. I think someone said the changed it halfway through the build year because people kept tearing rears up because of the gearing in first. Not sure the legitamacy (sp) in this . Thanks for the replies

 

really??? well s**t ya learn something new everyday...
