I have a 67 GTX 18 spline 4spd and after putting the car in neutral at a stop light it is hard to put into 1st gear, I have had the trans gone through and with new synchros/brgs from the kit from Brewers as well as put in the newer style roller bearing pilot brg and am using the Amsoil 75/90 synthetic gear oil that is GL4, the trans will down shift fine in all gears, its only when put into neutral at a light and than back into gear that it is real stubborn to the point that sometimes not sure it will even go into 1st or 2nd gear.
Any ideas would be appreciated. Thanks.
I would say based on your description that the most likely candidate is,
Improperly adjusted clutch creating drag. An indicator of this is how close off the floor does the the car start to pull the motor down and move ??
Pilot bearing / input shaft issue, again creating drag.
Mis-alignment of the bell housing, again creating drag.
An internal Trans issue.
keep us posted
