Hey guys,
Either something slipped by me or something needs to be clarified.
With the exception of certain aftermarket overdrives (that should not offer any real advantage on track) the car must have a transmission offered by the brand, same as rear axles. Same as before. There is no "any manufacturer goes" written anywhere I can see.
The OD tranny allowance was to allow people to play along with dual purpose cars.
Just to clearify- I want to make sure everyone can quote our rules properly.
11.00 DRIVETRAIN
11.01
Cars that were only available with a manual transmission may not convert to an automatic. And vice/versa.
For example: 1966 & 1967 Ford Fairlane 427 2x4 only came from the factory with a manual transmission, so an automatic would not be legal. 11.02
Any OE transmission may be used if offered by the vehicle brand. For example: an Olds with a TH400 could change to a TH350 or Powerglide, and a Chevy with a Saginaw could change to a Muncie or other GM 4 speed trans. Transmission casting numbers are not a tech issue. Internal modifications are OK.
11.03 OEM appearing aftermarket cases are OK.
11.10 Automatic Transmission:
11.11 Any torque converter is OK.
11.12 Shifter must be stock appearing.
11.13
Maximum 3 forward gears from first to direct.
11.14 Aftermarket Overdrive automatics are allowed as long as they are in a 3+1 configuration (ie GM 700R4, Mopar 518, Ford AOD) 11.15 Manual Transmission:
11.16 Any clutch/pressure plate assembly is OK. Scatter shields are OK.
11.17 3 speeds may be upgraded to a 4 speed.
11.18 Shifter must be stock appearing.
11.19
Maximum 4 forward gears from first to direct.
11.20 Aftermarket Overdrive manuals are allowed as long as they are in a 4+1 or 4+2 configuration (ie Keisler 5 and 6 speed & Richmond 4+1 OD 5 speeds are legal, however a Richmond 5 or 6 speed with 1:1 5th gear would not be legal) 11.21 Drive Shaft:
11.22 Aftermarket drive shaft is OK. Maximum 3.5” diameter.
Aftermarket drive shafts should be painted, to appear as stock as possible.
Let Them All Run
