MAJOR UPDATE
hearing how i was not happy, the Owner and Main Tech flew over this AM.
the master tech and I discussed all the instructions on how to adjust. as found trans detent was up in 2nd. ajusting to bring two detents together, holding in 2/3 center to loosely jam nuts. To me it was such a GREAT improvent. as I sat going through 1 thru 5 smoothly. Tech and owner had to agree it was better. the tedius came setting jam nuts. first try 1 thru 5, but no revered, second try reverse but no 4 & 5. sever trys got a good compromise to get all gears (not perfection, but very drivable.
ALL linkage was new bought assembled. (I might even have a new shifter)
So I can now drive 5177. It just makes me nervous (and scared), after driving pick up, this thing is QUICK.
