Junky has a 93 6.5 with tranny and tcm and db2 and wiring. Man that sure seems like enough parts to convert my burb to a DB2...Would it work with my tranny ? Even has the cruise control box....

91-93 used a 455HZ lock-up solonoid where as 94+ used a 800HZ solonoid. Stock 91-93 used a unique wiring harness, but most have been upgraded to the 94+ style by now. Also the valve bodies for the 91-93 were unique from the 94+ units due to the differrent lock-up solonoid frequency(the lower frequency solonoid required a cleaning cycle evy 5-10 seconds where the PCM would pulse it to clean it whereas the 94+ higher frequency units eliminated this cleaning cycle). 94 is a one year only unit with the new style electronics but no NSBU switch mounting bosses. 95-96 are the same as 94 except they added in a NSBU switch and mounting bosses for it. 97 switched over to what is known as teh rear luber where one of the cooler lines was relocated to the rear of the case and teh cooler lines was sized up to improve lubrication. Mid year 99 seen alot more changes to them internally mostly to improve the holding power(increased the width of the bands and changed input shafts). Later trannies can be made to work in earlier trucks with a trans cooler line adapter and valve body swap for the 91-93 units.
