transmission problem with my diesel k5 blazer

[4pilgrim4]

Been there, done that several times with my 83 diesel Jimmy.

First, pull the pan. If you see lots of metal, e.g., pieces of Torrington bearings, shavings and the like, your 700r4 is likely toast, but it still might go a ways. Likely the filter will plugged with the debris, so if you stick a new filter in and it goes, you might be surprised how far it will go!

Several years ago I had mine go out several hundred miles north of Los Angeles. With a new filter and fluid change I successfully got to a recommended shop in Pomona pulling a camper. This place dealt mostly in off-road, rock climber type vehicles. Once apart, the clutches were like new, but all the hard parts including the case were toast. The owner figured it was either the fourth gear planetary or a loose vane in the torque convertor that went first.

Anyway he built up a beefier unit with a special valve body for the use I put it to and it has been just fine.

If I had been home I would have opted for a NV4500, but that would have been a stretch on a trip.
