[C38] Discount Parts

[William Knowles]

Thanks Tom I will get under there in two weeks. I had new cables installed
last year but it did not solve problem and the yard guys are just guessing
at 90 bucks an hour. I can shift by hand down below even before the new
cables. When I shift in reverse there is a slight hesitation I think it is
that the lever on the transmission is not going all the way back. One other
weird thing last week while backing I could not add any power, I know the
cables are not connected but I could not add any RPM's, as soon as I got it
in forward (very hard to shift) no problems. Also somtimes shifts by itself
into forward that now makes sense if the cable is wrong not really all the
way in neutral.
Thanks again will let you know how it turns out
