I have gotten very good advice before on YT. My dilemma is the transmission failed on my last expedition pulling a IH 300U home. I have had three thoughts about the 92 Suburban. 1 Knock it in the head and get something different. 2 Put a manual transmission in it which at first is appealing but I have issues with the electronics and speed control I have not quite figured out unless I can find the perfect donor.3. rebuild what I have. So far I know it needs front and rear seals, wiring harness leaks, a vent broke probably all new discs and steels O-rings etc. I am thinking because the oil was real black, torque converter. I live in the rust belt and most of what I look at is rusted real bad and to get an equivalent is going to be over 6-7000. My Suburban is a Heavy duty C2500 with next to no rust anywhere under or on it. It is a 5.7 so a little under powered. I probably will be into the trans for 800 or more for parts depending on what I find when I get it apart. The still not sure if I should change the solenoids and what about shift kits, the wiring they changed the harness so it is a different style plug( which I haven't figure out if it is the new style) so would have to rewire the truck side harness. I have looked for used ones but am now out 150 or more miles and then it maybe junk when I get it home. How hard is it to do one yourself?
