Know anything about turbodiesels? 700 1985

posted by  someone claiming to be Brad Peterson on  Sat Oct 6 08:37 CST 2001 [RELATED]

My '85 740 turbodiesel has AT with lockup torque convertor. Two questions: 1) Is there a way to delay lockup from the present 49-1/2 or so, to about 55 mph? It doen't have the little overdrive switch on the gear selector. 2) Can I do anything to increase the boost a little bit? I don't want for a rod to put someone's eye out, but I'm looking for a little more oomph when the torque convertor is locked up. It goes great except when trying to pull grades at highway speed, and dowinshifting at 50-55 mph makes me cringe; maybe I worry too much, but I hate to see anything much over 3,000 rpm. Thanks.
