I have a 97 Cherokee Sport XJ and the transmission only shift into three gears...I traded for this and just put in a new 242j T Case. drove it and shifted finr thru three gears. My question, is this a three speed or a four speed w O/D transmission. How would I find out.

The AW4 is a 4 speed transmission (whats in a name) and yes, "has OD".
You can tell your torque converter locking up by seeing the rpm's suddenly drop somewhat when going past +/- 70 km/hr (you will have to convert that to mph for you guys).

Gee oh Dee

Could be a bad shift solenoid, but I'm not an auto trans guru.

Could well be, but that wasn't the OP's question haha.

Gee oh Dee

Still valueable information to know.

It's an electronically shifted, if the OP wants to fix it that may give him a jumping point to start researching.

Thanks for the info. I don't know what transmission is in the jeep. I am guessing it is the AW4. It is not shifting into 4th. I am going to try filter and fluid change and the shift solenoid.

There are 2 solenoids I do believe in the AW4 someone correct me if I'm wrong.

2 shift solenoids and 1 for the OD.
