Hi, I have tried to identify this trans.
Its in my civilian 1955 Fargo Truck, I think its a T98 Acme, but not 100 % sure, it's definitely20180113_160652_resized_1.jpg20180113_160647_resized_1.jpg not a NP 420.
Does anyone have an idea on this trans??thanx in advance....

Yes it is a BW T98 from the looks of it. No tag or casting #s on it?

Does the mounting foot at the rear of the case face forward or rear extended?

Hello and thanx, trans case is greasy, and no tags. Im pulling it tomorrow for a good look, been driving it for 5 years.

On the case between the rear of it and the brake there should be a mount. If the mount is straight down and 90 degrees to the front its forsure a T98.

There also should be a stamp on the upper housing cover. It should have a T98 stamp on it. on the passengers side of the upper cover.

You can also remove the upper cover and count teeth. The T98 will have a 43 tooth first-reverse sliding gear (the rearmost mainshaft gear, spur cut) and a 17 tooth cluster gear (also spur cut).

This trans looks pretty good inside and was working well enough. Is there kits you can buy for these anymore?
Anyone know the gear ratios and spread for this if its a T98 Acme? thanks

T98 and a T98A are identical.

6.40, 3.09,1.69,1.00 and 7.82 rev

The T98A has heli cut gears unlike a t98

I think the only other difference is a bronze gear on the 3rd shaft
