I'm Awesome
So I went looking for ZF specs;
ZF-6
Used exclusively in 89-96 [FONT=inherit !important][FONT=inherit !important]Corvettes[/FONT][/FONT], the ZF six-speed is a massive, durable, and expensive transmission. Rebuild parts are hard to come by. (Vette warranties required trading in a bad trans to [FONT=inherit !important][FONT=inherit !important]GM[/FONT][/FONT] for a remanufactured unit.) The ZF shares no common dimensions with traditional GM manual trasmissions. Its nonstandard bellhousing accepts on a Vette pull-style hydraulic clutch. Versions used behind the LT1/LT4 and DOHC LT5 engines have different length input shafts. GM usses a dual-mass flywheel to reduce noise from this massive, truck-like trans.
Pro: among the strongest steet transmissions available; closely spaced gear ratios; top two gears are overdrive-great for Bonneville top-speed racing.
Con: rare and expensive, no conventional trans mount, nonstandard trans-to-bell-housing bolt pattern, rebuild parts scarce, wide girth causes clearance problems.
gear ratios: 2.68 1.80 1.31 1.00 0.75 0.50
weight 145 pounds
rated strength 450 lb-ft
T56
The high-tech Tremec (formerly Borg-warner) T56 is installed in 93 and up V-8 Cammros and Firebirbs, comprises the front half of the C5 transaxle and withstands the most brutal abuse of torque monster V-10 Vipers. The latter features special gear metallurgy and may be the stoutest streetable manual trans yet. Production T56's use nonstandard bel-housings, electronic speedometer, and pull-style hydraulic clutches. The overall length, mount location, and internal-shifter position are different then classic-[FONT=inherit !important][FONT=inherit !important]muscle[/FONT][FONT=inherit !important]car[/FONT][/FONT] transmissions.
Vital Specs
Pro: a durable, smooth-shifting, high tech trans with double overdrive,
Con: production versions have nonstandard mounting provisions and no mechanical-speedometer provisions, limited gear ratio selection.
Rated strength 450 ftbs
weight 131 lbs
