Need the final drive ratio and rear end gear ratio

for a 03 sedan auto. I'm have the autoenginuity scan tool and it includes a dyno test also. But I need to load this information.

Thanks

hey if you want to weigh the car go to a land fill and pay them to weight the car with you in and out of it. I got the idea from sflg35.

This might get you close enough. This is the ratio from the 05 AT 3.357 per the service manual.

For speed tracer youw ill want to put in the gear you want to dyno at the time. IIRC 3rd or 4th fopr the AT is the most commonly gear dynoed.

I am jealous. I just bought my codes and my rs232 to usb connector started going bad so I just paid to have my connector upgraded to pure usb. Let me know how it goes.

These are the 05 6MT Ratios
1st 3.794
2nd 2.324
3rd 1.624
4th 1.271
5th 1.000
6th 0.794
Reverse 3.446 - just in case you want to dyno in reverse, hey you might need to back out of a sticky situation one day.

Looks like 4th is the gear. But I guess we just have to guess when it's in 4th (ie.. by manually putting it 4th) by couting the shifts. But when you mash the gas, how do you KEEP it in 4th? (ie no downshifting?)

If you're still looking, OEM rear end ratios are 3.538 for MT and 3.357 for AT.
