Is it possible to chance the 4th gear ratio in the 4 speed to get a lower RPM on the highway?
From 1:1 to maybe .80:1?

thank you

Possible yes, not sure if anyone offers an aftermarket gear set though.

when i was shopping around for parts for my super t-10 all the 4th gear sets i found are 1:1 nothing else was lower. which is why i went with a t56 first gear is useless but does launch quickly...lol but in 6th gear doing about 65 i am at 1500 rpms music to my ears

Where did you get the T-56? I have been looking for a T-5 and only found one in a '91 S-10

93'-97' LT1 F-body
98'-02' LS1 F-body
04'-06' GTO
04'-07' CTS-V

Those are donors for a T56 - GM.

03'-04' Cobra

Basically same transmission, but weaker input shaft.
