Woohoo!!! Fixed my acceleration problem!

Well after being beaten by a manual VK commodore I decided that I'd see if I can find where some of my acceleration problems are. I decided to change my speedo gear as I have a 3.23 diff, yet the speedo gear in my Auto was for a 3.08, so I thought this may effect the 4 speed Auto's shift sequence.

Well I've changed it now, and the acceleration is much better!! Before the auto would change up at gear at around 3900RPM, now she smashes into the 5000RPM redline before changing up a gear! Obviously the 4 speed Auto has some type of error control and shifts the Auto up early if the speed is too high.

I'll be taking it to the dragway this weekend and racing it against the manual dunnydore, but I'm pretty sure I'm going to kick his ass now. Woot. I'm hoping to get at maximum high 16's.

If any of you guys have a dodgy speedo and a 4 speed Auto, I suggest you change it so you can get the most out of your car. I jst found out Ive been missing half the fun.

Re: Woohoo!!! Fixed my acceleration problem!

Good stuff man, I never thought it would affect the performance of the gearbox. If your 3.08 gear would fit in a T5, I may be interested in taking it off your hands too.

It will, I have Rollins 3.45 gear from his T5 in my Auto and he has/had my 3.08 gear. they are interchangable

Re: Woohoo!!! Fixed my acceleration problem!

So auto and manual speedometer gears are interchangeable?? That's good news for me, I no longer have to look for a EA manual with a 3.08 diff in it!

How hard is to remove/replace the gear? My speedometer is way off at the moment. I think it's a combination of the 16" wheels and the diff :-S

Re: Woohoo!!! Fixed my acceleration problem!

Sunny, I was pretty sure they were interchangable anyway, because my current sender is from my 3 speed auto (thus tuned for the 2.77)! I'm told it's not a very big job to replace, but beyond that I don't know much. :o)
