As the title says gears for a family grocerie getting burb
I believe 3.08 was only offered in the diesel Burb for the first few years. 3.42/3.73 are the other possibilities.
Most 3/4-tons have 4.10 gears and a TH400 (not OD). They're okay for city driving, but suffer on the highway. I swapped a 3.21 axle into mine for this reason.
IMO, look for a '91 3/4-ton. You avoid the fragile 10-bolt and small 1/2-ton brakes, and get a 4L80E (OD trans).
Keep in mind that if you are going to run a 700R4 even with the low stall deisel converter that you need to try and keep the RPM's up a little bit so you don't lug the motor in OD and put extra heat in the tranny.
I would say run 3.42's or 3.73's and a big cooler. This is especially true if you are going to up the tire size over stock any or are going to tow any.
3.73... ford chevy and dodge all use 3.73s standard in their new diesel trucks. other ratios are optional.
That is a cool fact to know I am still thinking for milage reasons if and when I get a diesel to go w/ a set of 3.42's for better milage. But I will most likely not be getting this rig soon. I have a garage and a house w/ all the things that go with it like septic system, driveway, well etc etc to work on currently. So my 82 dd will most likely be the only vehicle I own for a bit (after I sell my other 2 trucks and the jetta anyway) But when I do get t the point of locating a diesel burb, then it would be for road use only going places and not hauling anything save for family (when I am fortunate enough to have one) and groceries.
my 83 came with 3.42 gears... Cruises down the highway great.
