Whew, the correct trans was used.

And they still think the pilot bearing is the culprit, as they have checked everything else and all parts look and function like new.

Man I hope that's it. Hate to button this thing back up and then have to do it again.

most of the time when a clutch drags, it is because whoever installed it let the weight of the trans hang on the input shaft of the trans thru the clutch bending the center of the disc--this makes it instant junk and there is no way to fix it except to replace the disc, using the proper alignment splines and long guide studs in the bellhousing to guide the trans exactly down the center without any weight being rested on the input shaft/splines

The pressure plate bolts may be loose, or pulling out. This is a more common problem with FE and aluminum flywheels.

wow. never heard of that before but makes sense. i'm a bit surprised it didn't grind into first but then again, reverse is a much lower gear. glad you caught it early and on are your way.

I hope they checked the bellhousing concentricity when the trans was out. That would be a primary candidate as a cause for a short-lived pilot bearing.

I'll know in another 1500 miles or so.

The problem reared its ugly head again in 700 miles.

However, this time it was the slave cylinder installation. They had to put a washer on the tip of the slave rod to keep it from slipping through the shift fork. The washer was just a bit too small and it was pushing through the fork slightly so that the clutch would not completely disengage. Put a larger washer on the end of the rod and the problem went away..........for now!

How did you wind up solving this? I have the same exact problem after driving for a while with a car with 1000 miles on it. Did anything relate to overheating the lines or the engine compartment?
