Re: turbo 350 to 235 six

Actually 2nd on a glide is 1 to 1 as there are only two gears.


Transmission/Gear 1st 2nd 3rd 4th 5th 6th Reverse
Powerglide 1.76 1.00 - - - - 1.76
Powerglide 1.82 1.00 - - - -
TH200-4R 2.74 1.57 1.00 0.67 - - 2.07
TH350 2.52 1.52 1.00 - - - 1.93
TH400 2.48 1.48 1.00 - - - 2.00
TH700-R4 3.06 1.62 1.00 0.70 - - 2.29
4L60 / 4L60-E 3.06 1.62 1.00 0.70 - -
4L80E / 4L80-E

According to the above chart a powerglide would be a lousy choice for a small engine with either the 1.76 or 1.82 gear reduction in low gear.
