Speaking of gear codes and the like, what do you do if the idiot who had the truck before you removed the VIN plate that has all that info on it? Can it be obtained by Toyota?

The non-neutral T-case was specific to ADD models. That's why some 22RE 4X4s from '89-'95 got a different tranny (G58) than the standard W56 found behind most 22REs. The G58 tranny came with a chain driven T-case and were installed on '89-'95 Toyotas 4X4s that that had the 22RE and ADD.

Where your truck might be different, is that I think most V-6 trucks came with ADD. But I'm guessing yours did not. I'll bet you have manual hubs. Your set up is already unusual in the fact that you have 4.30 diff gears and yet a manual tranny. The 4.30 gears are usually reserved for automatics with the smaller 225/75R-15 tires. And speaking of that, I assume original tires on your truck were 225/75R-15? If so, then your gear ratio may really be 4.10, or if it really is 4.30, then you must have some sort of rare tow package. Do you have a factory or dealer installed hitch or wiring?

If it is possible to have a neutral in a factory chain driven T-case, then the likely explaination is that Toyota just installed neutrals in T-cases without ADD as indicated by my owner's manual. On the other hand, if neutral were not possible in a chain driven T-case, then I assume, you must somehow have a gear driven T-case.

Have you confirmed that you have a chain driven T-case by the number of bolts on the back of the T-case?

Yep, I have manual hubs. Original tires were 225/75/R15. I have a "tow package", whether it is from the factory or not I don't know. It has a ball on the bumper, but the wiring doesn't really look all that "factory".

As far as the gears, I've double checked by lifting one tire and spinning. I'll have to do that again though.

I have not confirmed the t-case by the bolt numbers, I'll have to check that next.

This *is* getting interesting. As a data point: My 88 Xcab (bone stock when I bought it from the original owner) had a V6, 4.10's, manual hubs, R150 tranny, chain driven transfer case with no neutral. I no longer have the truck, but the transfer case is sitting in my garage.

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.

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.

well I'm tired of looking for the tcase picture on Marlin's website, but anyway, I have 12 bolts on the back of my tcase. If that sounds off the wall then I'll go out and look again. It's chain driven though, I remember seeing the chain when I drained/filled the gear oil a while back.
