hey guys, im looking at putting in a new TC and im trying to figure out what stall speed would b best for faster take off, but also doesnt compermise normal city driving comfort.

Does anyone know what the stall speed is on the OEM TC on my 92 SC4 is so i have a baseline?

Also does anyone have any recommendations as to what the best stall speed would be?

Thanks

2700??? No way. The stock tc's are max 1800 rpm. I would get one atleast 2700-3500 rpm stall speed tc's. And if you really want to be able to launch add a tranny brake!

Page SS-42,Volume 1,Lexus 2000 Repair Manual RM715U1: Auto Transmission A340E,"Engine Stall Revolution, 2700 rpm".

Page SS-44,Volume 1,Lexus 2000 Repair Manual RM715U1: Auto Transmission A650E,"Engine Stall Revolution, 2250 rpm".

These values are also referenced several times in the diagnostics pages (DI-336,DI402) of the same factory manual.

Then why would you need to modify the tc? the A650E that comes in the IS300 I know for sure isn't 2250 stall speed. I have a Level 10 tc with a 2800 rpm tc, and the stock one was measured by Level 10 at 1700 rpm.
