Well i think its time for a new gear for the t/c and my truck.Im shooting for mpg's on this let me know your thoughts. The t/c has 3.73 in it now its a 5 speed and is still a bone stock 2.3 yes i know it gets about 31-32 mpg highway now. im thinking 3.27 or 3.08 just not sure give me your thoughts. Now the truck is a 2000 f150 auto 4x4 5.4 v8 again its got 3.73 this truck no longer pulls anything but my family. i use my dads f 250 to do all my pulling. im thinking 3.55's or 3.27's for both axle's on it. any thoughts will be helpful.
On the truck 3.73 to 3.55 wouldnt really be much difference in MPG or RPM.
On the TC, I would wonder if that lower gear would cause the engine to lug down and have to boost to even go up very small inclines. Which will add more fuel when boosting, your MPG may go down. Maybe 3.55 on the TC.
Putting a higher gear ratio in the TC would be a mistake. 31 mpg is hard to beat even in a brand new car.
Agreed. I'd leave well enough alone personally.
Leave the gears in the TC alone.
31 mpg is frkkn amazing. Just like 50brd88 said, some new cars can't even get 31 mpg. Be happy :)
I've got 2.73 rear end and only get about 35 mpg highway. So not really enough difference to be worth it in my opinion.
Here, I fixed it for you.
If you're only getting 25mpg highway then you need to get your foot out of the carb. Hold her steady around 60 mph and you'll get 35mpg like me.
ill leave the TC alone and who knows about the truck just yet .
