I have a 70 280 se which I inherited from a95 year old aunt several years ago. It has 150000m. This vehicle looks like new and has always been proffesionally maintained. There are afew problems with it that are unnerving though. One is the 3rd gear flair. Other gears are just fine but 3rd which has such a nice powerful gearing just seams to slip.New tranny? Repair? Adjustment? I tried Transx afew years ago w new fluid ect but it stayed the same. The other thing is thatr after I pull off highway warmed up cruising speed, and stop at stop[ sign the engine invariably kills. Runs and idles perfect cold or cruising around but after high speed doesnt idle. Any suggestions?
