I have an opportunity to pick up a Tremec 6-speed that was factory installed in a C-5 Corvette. Anybody have any clue whether or not it can be modified to bolt up to bellhousing for the 351W? What may be some of the peculiarities of this particular transmission?:confused:
The C5 Vette uses the T56, but the tranny is rear mounted... (LS1 engine, clutch, torque tube, tranny, then rear diff) I don't know how that will affect it's ability to be adapted. Having owned an LS1 Camaro with a T56, I do know that the LS1 version of the T56 does not lend itself to swapping onto other engines. I know for a fact that an LS1 T56 cannot be adapted to a small block Chevy... Stands to reason that the tranny needed for an SBF would be the SBC version. Therefore if the SBC and LS1 trannys are incompatible, that it wouldn't swap with the SBF. The standard T56 is fairly weak. The syncros are cardboard... literally. The input shaft is weak. One of the 2 internal shift rods bends easily. The way around these weak spots is to either install the Viper spec parts or use a Viper spec tranny. The Viper: Syncros are kevlar. Input shaft is hardened. The shift rods are steel. Good luck Dave Edit: The T56 is a Borg-Warner design. It has been around a long time and B-W wanted out... Tremec bought the rights to the design in late 98. The better T56s are said to be the ones marked "Borg-Warner". The Tremecs are said to be even weaker... at least on the LS1 boards I am a member of.
6 speed i used to adapt top loader 4 speeds from a ford to a sbc or a bbc very easily. so if the bolt patern is the same then it will probably adapt. ck it out
Another thing is they use an electric speedo.They make a viper spec t56 to bolt to smallblock fords,but the gm version is not very adaptable,so I've read.
That was my point exactly... He is looking at an LS1 tranny, not an SBC/BBC tranny. The LS1 tranny is a completely different animal and will not adapt to the SBC/BBC, therefore I doubt it will adapt to the SBF. I forgot about the computer controlled speedo... These cars do not use the tranny at all for the speedo. They use the ABS sensors for speed readings. You would have to hook an aftermarket speed sensor to a wheel or something, unless you got a swap specific tranny. Dave
In my opinoin the six speed has no advantage over the 5 speeds availible, except for cool value. If you compare ratio's for each gear the six speed has an extra gear between 4 and 5 on the 5 speed. This would be great if the 6 gear was significantly taller than the 5 speed trans but it's not. Or have close ratio 5 gears with an overdrive. Then you could set up for excelleration and freeway cruise. I just can't except the cost for coolness, unless you get the trans cheap or free. my 2 sence
BINGO!!!!! I was going to get the deal of the century, but after reading all this good info, I probably will not fool with it. Thanks for the info, guys!!!
Terry, I suppose if you wanted to go nuts, you could put corvette suspension in all 4 corners, and then use a vette drivetrain to use the trans Shaun
Well...it would handle better, but I only want to do that slightly more than I want to cut off my legs.
