Can anyone tell me what the trans ratios are for a Warner Gear T-98A transmission are? I think this trans was available in some fullsize jeeps. Is there any difference between a T-98 and a T-98A? Thanks

from what i understand, its basically an older T18 design

so ill assume its available with a 6.32:1 first, and possibly a 4.0;1 first, and 4rth is 1:1

just like a T18a, i KNOW its availble with the 6.32, Im speculating on the 4:1 first version.

Advance adapters lists first as being 6.40, 2nd = 3.09, 3rd = 1.69, 4th = direct.

It's not exactly the same ratios as the T-18, but it's pretty close. Partsmike claims that the T-98 has bushings in a couple spots that the T-18 uses bearings in and that's the major difference. About the same strength, but harder to find parts and adapters for. Supposedly the cases are interchangeable in some cases. (Sorry 'bout the pun.)

I had the t98a. It was a 6.4 to 1 1st for mine. It was out of a ford, but likely they all were 6.4 to 1 (all though i'm not sure.) T98's and T18's are very similar, but not interchangable internals. I used my t98 case and put in t18 gears/shafts (i got a t18 with a cracked case). The t18 is updated and better than the t98 for durability. hope this was of some help. jamey williams.

My memory stands corrocted! 6.4 it is

ill bet that 0.08 extra really makes it outcrawl a T18!
