I was at a local car show and I was in heavy stop and go traffic with the T on a 5% grade. At the end of the day, whenever I had the car in low gear and pressed the clutch to the floor the car had very slow acceleration in low gear, and once I was able to shift into high, it was fine. Low gear was only useful up to about 5mph. Even while increasing the throttle. I'm concerned if I burned out my low gear band? Can it be adjusted?

The "Low" band is the one that is easily adjusted.

Remove your front floorboards. Sticking out the right side of the transmission is a large screw with a lock nut on it. Holding the screw's head with one wrench, loosen the locknut with another. Then screw the screw in.

Test the travel of the Low pedal as you adjust the screw. You should have about 2" below the pedal to the floorboard when it's mashed down, but that's hard to gauge with the floorboards out. So, just make sure you don't get it tight enough that it 'drags' when the pedal is not pressed. You can often tell that by sound.

Then re-tighten the locknut, put the floorboards back in, and you're done.

If you can't get the band tight enough to make things work correctly, then you need to re-line the band. That's a whole nother kettle of fish, and you need other instructions for that.

Yeah "T's" don't like the stopping and starting in low gear if you have to let the traffic get ahead of you Make sure you have enough distance to engage the low band and let it crawl do not try to "Feather" the low band if you do you may smell hot oil in short order

Jonathon, if you actually got to the point of it slipping heavily while driving, i would take a quick peek at the condition of your bands and drums before i just adjusted it from the outside... Just my 2 cents.

Side note, I never smelled any burning oil. I just felt as if low gear wasn't letting the car accelerate enough to get it into high gear.

The low band can be adjusted from underneath, no need to remove the floor boards.
