Your post is a little confusing. I believe that the guy you are buying it from is referring to this transmission as a non-electric 4l60. In the later years the 4l60(700r4) was changed over to a 4l60E which must be controlled by a computer. The 1989 is a lock up transmission that the lockup convertor can be controlled by a computer(factory in the later years) or with an aftermarket lockup kit such as B&M or TCI. It is even possible to fabricate/create your own torque convertor lock up kit. Please post some more information about your vehicle and exactly what you are trying to accomplish. Good Luck.

here is a wiki article that may help a little for converter lock up control on the 700r4. The article needs a little fine tuning

Dont worry how old you are... it is the mileage on your body that adds up.
