thanx alot !

 

is your transmission stock? On a stock valve body the 1-2 shift takes about 1 second to happen with 3.27 gears your motor will rev about 1,000 RPMs a second so you need set the shift point below where it is actually going to shift. With 3.73s your motor revs up faster so you will need to reduce the 1-2 shift even more or you will hit the rev limiter at WOT.

I have 4.10 gears and a blower I have my 1-2 set to 4,750 actually shifts at about 5,800, I have my 2-3 set at 5,700 and my 3-4 at 5,300. You need to play with it a little to find the best shift points for your car.

 

i just install 3.73 gear, my transmission is stock, so what you suggest for my case? ( before i play with it cuz i dont want to do somthing stupid)

 

I would read through this write up 2/3 of the way down it explains the 1-2 shift.

As far as setting your shift points, I would start with stock and see how it does and gradually drop it down.

 

this is my set when i checked the settings in the predator

shift points: 1-2 : 5950 (was 6100 !)
shift points: 2-3 : 5700
shift points: 3-4 : 5700

any suggestion? somthing good but wouldnt hurt the car?
