<strong>can i complicate this even more? i have T100 that came with a 3.4L V6 and A340F auto trans. the code on my VIN plate was A11A/A340F. the truck came with ADD and has a "neutral" on the transfer case. it has 4.30 gears. i always assumed this was chain driven. it is 5 bolt at the rear output, so i guess it is a chain.</strong></font><hr /></blockquote><font size="2" face="Verdana, Tahoma, Arial, Helv, Helvetica, Sans">You have an American built truck, which is why the gear code does not match those of the Japanese trucks. Also, the T-100 uses unique gearing compared to the compact trucks. The gear ratios available for the later model T-100s, which I assume you have since you have the 3.4, is 3.91, 4.10 and 4.30. The 4.30 being available for the auto tranny like yours.

It's interesting to note that the first T-100s, that came with the 3.0 V-6 got much different gear ratios. They 4.56, 4.70 and a whopping 4.90 as available ratios. Very rare gears I'm sure, but because the rear is a Tacoma style diff and the front a pre-Tacoma style diff, the gears aren't easily swappable into a compact truck.
