wiring in a late model 700r tranny

we have a 84 suburban w/200,000+ miles on it & the 700R tranny is starting to show signs of wear, the fluid is starting to stink & and is dark I have been told my tranny is one of the weaker ones (hard to believe w/200,000+ on it) and that I should look into getting a later model one because they are better. So my question is this how do you wire in a computorized 700R tranny into a non-computorized truck...thanks.joe

It's hard to believe an 84 700R4 made 200,000 miles in a Burb without a rebuild. Someone drove/maintained it remarkably well. I would go for an 88-91 version and put in a Painless Kit that handles the lock/unlock with no problems. Having said that, I dont know why what you have on the Burb now will not work fine, because they did ot change significantly until 92.

hate to disappoint you trees but i dont use my truck "I ABUSE IT" , of that 200,000+ miles at least half of it was pulling a 5-8000lbs trailor behind it along w/working the dog snot out of it & driving it HARD . Oils is changed about every 5000miles & tranny fluid is changed once a year at least. Other then that all I have done to it really is a timing gear & chain. Not bad for a truck that only had 32,000 on it 7yrs ago...........joe

700R4 Suburban.

If you are going to purchase a good used unit then try and find one from another Suburban or full size Blaser up to 1992. if do not then the shift feel and shift points will not match your vehicle and the torque of the engine.

TwoMany, that is awesome!! I would have that baby torn down, and rebuilt just the way it was, just to see if if it would do it again. (all the tranny builders I know say a rebuild will outlast the OEM ) You must have the record miles on an 84 700R4 and it is growing!!

Paul brought out a good point. You will need the same governor springs to match the Burbs weight and HP/torque.

Just me but I would say your answer is right there. True regular fluid servicing doesn't guarentee anything but I change my oil every three thousand miles in every car, coolant every spring, trans every 25,000 miles, and I average over 200,000 miles on every car I own before getting rid of them. All my Nissan trans have gone over 200,000, my old Dodge Dart-well over 200,000, and my wifes '90 Caravan had almost 250,000 miles on it before we sold it for 500 bucks and I towed my bike trailer with that all the time. Maintenance, maintenance, maintenance! Not a guarentee but I preach it religiously.
