Gotta love those transmissions.

Shoulda said trannies.  Then Aaron woulda popped in.   :confused:

I actually edited my own text. It was tranny, and then I backed it up.

Ok Brian got a question for you.  I am going to a bigger tire (35x12.50x17) and I was told to bring my truck in to have them change the pinion factor.  I am assuming that it will change the speedo and possibly shift points, am I any where close?  Thanks

If they don't change the ring/pinion then your speedo will read slow.  And it will be a turd.  I don't see how shift points will be affected.  What gears do you have now?  It would be like taking off in second gear all the time if you didn't regear.

The formula is   Tire Diameter (inches) x RPM  /  336 x Gear Ratio (transmission) x Gear Ratio (Ring & Pinion ratio)

For example,

30 inch tire x 3000 RPM ( = 90000)
336 x 1.00 (third gear my truck) x 3.54 (my axle ratio) ( = 1189.44)

90000 / 1189.44 = 75.67 mph

Throw on taller tires only:

35 x 2571 RPM = ~90000
336 x 1.00 x 3.54 = 1189.44
Still going about 75 but your speedo will read 65.  You are turning less RPMs so your speed will read low. 

In this case, 4.10 or 4.11 gears would be closest to what you want.

With a non-lockup automatic you are supposed to add 10% or something RPMs to allow for torque converter slippage but let's keep it simple.



I'm making this more difficult than it is but look at it and play with the numbers and you'll see it.

Correct.

Disco pretty much hit it on the head.

And spend more on gas.     :'(

Yep......I'd think twice about lifting anything with the way stupid gas prices are.

I know someone that is using used tranny fluid for fuel.  He swears it works.  Doesn't even throw codes.   ???
