Challenger Transmission Tuning

[Cruizer8]

I recently ordered a Dodge Challenger Scat Pack in real life and I am trying to create a rough approximation of it virtually. I have most of it setup, but when I try to tune the transmission gear ratios to match the actual car, I am unable to get that low.

Gear / Real / Lowest GT6
1 / 2.97 / 3.444
2 / 2.10 / 2.393
3 / 1.46 / 1.782
4 / 1.00 / 1.391
5 / 0.74 / 1.139
6 / 0.50 / 0.833

Is there something I am missing that would make these ratios different or am I just SOL in making them match? Any tips on getting it setup like the real thing?

I cannot match exactly without knowing your power parts installed, but I managed to build it with these steps.

Install sports exhaust, isometric exhaust manifold, and intake tuning. Set transmission final gear to 3.500, then set top speed to 273 mph.

If you post the parts you installed I can fine tune it closer to your parts instead of my parts.

That gets me close enough. 5th and 6th aren't quite as low but close enough to not care. Thanks for your help, I didn't realize adjusting the max speed changed the available ratios.

I would suggest messing with the final gear a little more followed by moving the top speed away and back if you want to get closer.

For a stock challenger SRT8 2008
final gear 3.500
max speed 273 mph
1-2,970
2-2,100
3-1,460
4-1,000
5-0,740
6-0,500

Then adapt final gear to reach a realistic top speed acording the real car .... or something like this.
