AW4 Transmission question.

[Pistol Gripper]

This is in a 95 Jeep.  If you manuall shift, it works great, if you leave it in drive, it starts out in high gear, will not downshift on it's own.  Any ideas on the cause?  Need more info ?

Thanks,

P.G.

Does it have reverse? when it starts out in 3rd, does it eventually go into 4th? Also, is this a 2wd or 4x4 and what model/engine.
