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
