New Body Style 7. T56 SIX-SPEED TRANSMISSION
This is the 1995 S-10 Blazer shown on the previous pages, but with a Borg-Warner T56 six-speed transmission from a 1994-1997 Camaro.
The transmission mount on the T56 is about 3.75" rearward of the 4L60 (700-R4) mount, so the crossmember was modified by removing the perch and drilling a 7/16" hole on top of the crossmember for the mounting bolt. Another larger hole was drilled on the bottom for access to tighten the nut.
The T56 rear mount places the output shaft about 1-1/4" higher than with the 4L60 mount, so the crossmember was modified so that the top of the crossmember is 1-1/4" lower than stock.
It should be noted that the 1995 transmission crossmember is the easiest to use to install the T56. The crossmember on 1996 and newer trucks and Blazers is different.
The 17-tooth reluctor ring in the transmission was changed to a 40-tooth reluctor ring so that the speedometer and anti-lock brakes work correctly. You can find more information on speed sensors and reluctor rings in this free download from our manual Chevrolet TPI & TBI Engine Swapping.
