3S-GTE Swap Guys -- Tranny and Gearing Related, What's it turning?? Options

[Fastbird]

For those who do have the 3S-GTE swap, couple of questions:

First, for those with the stock GT tranny, how are you finding the gearing and relative ability of the tranny to handle the power.

Second, for those with the E153 tranny, how is it's gearing compared to a stock GT's??? More or less RPM's at highway speed?? Better (shorter) gearing off the line or taller gearing??

Does anyone have a breakdown of the specific gears ratio for each tranny??

Thanks!! (I did a search but came up empty on this one)

That's EXACTLY what I was looking for. Looks like the E153 tranny is the way to go.

My main concern is going to be the 4000 RPM's at 80 MPH in the GT tranny with the motor swap. That's going to be making boost no matter what the engine load (MAP) is, thus killing gas mileage. Not that it's a big concern, but obviously a .72 overdrive is going to be nicer than the .82 overdrive.

Amazingly enough my 93 Trans Am has VERY close gearing to the GT celi but an added .62 overdrive and final drive of 3.23 stock which makes all the difference.

Now the question becomes.......is there a way to change the final drive ratio or a way to have a custom gearset made for the tranny??
