It would not. You are giving up your best acceleration gear. Heck, If I had a motor that could be wound up to a gazillion RPM, I'd run first gear the entire quarter!

I'm an old school guy most of the time...maybe even a bit of a dinosour...but there are some problems that have very firmly worked out solutions, tested, re-tested, and tested some more.

If you are putting down enough power to spin the tires on a drag strip, then the goal isn't to limit the power output by dumping the gear ratio. May I suggest the following solution.......

Awesome pic Curt and in the kitchen too, gotta luv that

hmmmm so it might work... but isnt worth it from what the consensus is..

now since im also old school how about some tips on a FWBO

Thanks, Momma'* away on a trip to Pennsylvania...no problem sneeking the Micky-T'* into the kitchen, unless the short person who took the picture rats me out...just gotta clean the black marks off the tile floor

hahaha short person lol

it would be good on a very high horsepower light car or dragster that y the powerglide 2 speed transmission is so popular but for a steet car its the opposite you need the lowest gear my 2 cents and old drag experience

Curt, your M/T'* have the same nasty 'dirty' paint in the letters mine did. I don't think mine were ever in the kitchen, but they were in the shower for awhile. And in the living room.

2nd gear start is for severe icy/snowy weather only. Worst thing for performance you can do.

No idea for a 4T80, but I've had the second gear start in my car before, it'* just a PCM programming function. If the gear selector was in the 2 position the car would start in second gear, very interesting with a stall torque!

Cheers,

The switches Pat is referring to are quite large. I kinda wonder if they don't include the relays/circuitry built into them.

Not really likely. The common way of doing this is to simply ground a pin at the PCM, or introduce a resistance across two pins for the signal to change modes.
