Thread: Chevy 2 Speed Auto Transmission--Opimions Please

On your questions, on a super lightweight trike I don't think that you will notice much difference between the PowerGlide and the TH350 other than the lower first gear ratio on the 350 which will give you a bit more pop off of the stop lights. Your 350 has a 2.52 1st gear compared to either 1.76 or 1.82 on the PowerGlide. Both are non-OD trannys with 1:1 final output, so I would think that your mileage would be the same. The only thing that might make it different is if your TH350 is a lockup unit with a controller to lock the converter in top gear cruise - you can tell by the electrical connector on the side, wired out to a box. The PowerGlide will give you one long acceleration gear into high, and your kickdown acceleration will be a lot stronger in the mid-range area where the 350 would drop down to 2nd. All in all I would think a PowerGlide would be a good tranny for the trike, but I'd probably opt for the Lockup TH350 or even something with OD on a new build. Others may disagree.
