A904: 1-2 shift happens early despite governor weight- any way to adjust this?

The trans doesn't have to come out to change the 1-2 shift spring, just drop the pan and valve body. It can be done in 1-2 hours.

I agree, the factory linkage is far superior to the lokar bicycle cable. If you must use a cable either build your own using junkyard parts from a magnum engined truck or van, or buy the bouchillon cable, which uses the same factory parts. It is a much better cable and brackets than the lokar.
