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.
