Do i need to do anything to my transmission?

[Josh97GT]

I have a 97 GT (Automatic) with 4.10s, I know my speedcal is a bit off, but I'm wondering if I need to do anything to my tans to fix my shifts or anything at all that people should do when changing gears that I haven't.


kthnx

you dont need to do anything. your shifts should be fine. if you want you can get a chip and change your shift points.

I thought for autos if you change gears you need to have your computer recognize it so it knows where to shift, if not you can damage your transmission. I think you need a chip or programmer.

Yeah i reprogrammed mine. 1-2 (-200) 2-3 (-200) 3-4 (+200) [i think] using a hypertech
I was bouncing off the rev limiter

 

[Josh97GT]

So auto's have to reprogram? anybody know for sure? I don't think something like speedcal can do this. (i don't have speedcal btw)

 

[DarkShadowGT]

from what i know they dont make a speedcal for autos. Speedcal just adjusts your speedometer. its the shift points you should worry about. try flooring it from a stop up to the one-two shift and see if you hit the limiter (or close).sometimes 4.10s makes your rpm's climb faster than your auto can think thus resulting in the rev limiter hit. so make the computer shift a little earlier so it has time to think (hope that made sense)

 

[Josh97GT]

How do I do that?

 

[DarkShadowGT]

hypertech or predator thing. hand held programmers or a custom burned chip

 

[tomustang]

like i said the first time, you're ok. BUT if you want better shift points get a chip (or a tuner)

 

[DarkShadowGT]

unless he was like me and hits the rev limiter at WOT. it happens to some people, not everyone has the perfect tranny.

 

[tomustang]

he's got a 97, not a new one. the tranny shifts should be perfect.

 

[DarkShadowGT]

oh i didnt know it works that way. i guess you learn something new everyday.
