Speaking of transmissions adjustment... I just replaced all the bushings and boots on my 87GL shift linkage. I am confused as to how to adjust. Thought I followed the Bentley instructions right, but now (although the shifting is really smooth!) I can only get it into 3 and 4 gear. It will shift into the 1 and 2 positions, but it is engaging 3 and 4. Found it hard to adjust the "band clamp" connection. Should I really open this up until it fits loose? I can't seem to get it to fit back on as far as it was...Any ideas on this? Thanks! Tony ------------------------- Randy Bergum wrote: > Hi Vern: > My '90 van used to buzz too.
