Clutchless trannys in SS Modified NHRA

What does NHRA allow in SS Modified, Clutchless 4 speeds or 5 speeds or both. Any help would be appreciated. Thank you, Mike

Recent rule change; you can now run clutchless in traditional SS and that trickles to the modified. Traditional SS still has to run the correct number of forward gears as per OEM.

55's and 56's are allowed to run 4-speeds. The Modified classes are allowed to run 5-speeds.

This is true, in any car that came with a 3sp manual standard, can now have a 4spd. BUT, this only came about AFTER nhra allowed powerglide combo's only, can have a 3spd auto. Man what a mess....I think there is a weight break diff between the Sticks and Autos in SS Modified? That needs to be lifted.

I still think modified stock is still limited to 4 gears, i thought that might be lifted beings i think lots of the newer cars come with 5 gears. Correct me if i'm wrong.

Yep, forgot about those 3-speed manual exclusions. So how much did those pick up with the 4-speed conversion? It sounds like those that lost the PG in exchange for a turbo type trans picked up a bunch.
