SWR,
Thanks for the link. Lots of info for sure.
Got a question for ya...
My '08 Tacoma DC OR 4.0L V6 AT should have 3:73 gears right?
(Tacoma Product Info for this year/model shows 3.727 to be exact), and others on this site have confirmed that as well with their '05+ Tacomas.
My door code is A04B. Do I have 4:56 gears per the chart?
Can you (or anyone else) shed some light on this? Thanks
WS
I don't want to tell you which gears you have and be wrong.
This is one of the best links I've found that will help you figure out what you have.

It helped me figure out that I have 4:10 gears from the factory, long ago, when I had no idea and I was new to Toyota.
Brian is also a member here at ExPo, but I have not seen him post up in a long time. Hope that helps!
The chart at the link in my earlier post, is to show you what gear would be appropriate for your choice of tire size. Not what gears are currently in your truck. Was that what you asked? Did you mean to say "do I need 4:56 gears". I'm just trying to be clear so nobody gets confuzzelled! I hate confuzzelled!:elkgrin:

Most calculators are built by Jeep guys who have larger displacement engines. I started on the ORC Yota email list in about '98. The common advise for 20/22R trucks since that time has been 31's = 4.56's, 33's = 4.88's, and 35's+ = 5.29'sI'm thinking about swapping my 4.56 gears for 4.88's as my 56's just aren't cutting it for power and pep with the tires and armor and gear. While most calculators will tell you 4.56's and 33" are perfect I think 4.88's and 33's would be much happier. Some tell me 5.29's are even better but man that seems to be a stretch. I know others running 4.88's and 35's getting better fuel economy than I do now.

Simpler way to do this is to draw a straight line down the drive shaft, then tape a piece of string to the drive shaft right at the drawn line. Rotate the tires one exact revolution. Look at how many times the string crosses the line and what the partial revolution is.snip.....
I think I'm going to go with the old fashion approach, put the rear of the truck up on some jackstands, turn the driveshaft, and note the wheel revolutions per turn. I'll let you know what I come up with when I have some time to get to that experiment. Thanks for the reply and your effort!
