Dave,
T176 (M) 3.52/2.27/1.46/1.00/3.52R Jeep '80-84
T177 (M) 3.82/2.29/1.46/1.00/3.82R Jeep '80-84
T178 (M) 3.01/2.08/1.47/1.00/3.01R
Jeep used the T176 mostly, but some were of the T177 gearing,which would be more desirable. The wierd part was they only called it the T176, no matter which gearing was inside the box.
regards, as always, jefe
