4 speed, Hard to shift when cold.....

694spd said
I'm have a problem shifting into 2nd when the trans is cold. Sometimes it is stubborn to go into 1st, but 2nd is the biggest problem. Usually I have to just skip the gear and just go from 1st into 3rd. After a few miles of driving the 1-2 shift will improve.
As for 3rd and 4th gears, there is no problem with those shifts.
I rechecked my shifter rod adjustments and made and a one turn adjustment on the 1-2 rod, but there was no improvement after that.
Last week I swapped out the stock Hurst shifter and rods for an aftermarket Hurst Comp Plus shifter and rods. I was real careful setting and checking the rod adjustment when I installed it, but again still I have the same cold shifting problem. When it does warm up it will go into second, but still with a little resistance. The other gears seem fine.
FYI, I'm using Sta-Lube 85W-90 gear oil, GL4 in the case and the car is a 69 340 Dart.

I use automatic transmission oil and have no shifting problems hot and cold, street and strip. You could try that with ease. Does your clutch disc move free on the transmission, clutch pedal gap? Car is moving/ spinning the wheel with pressed clutch pedal, if the clutch is the problem. I had one car that was hard shifting to second gear because somebody forgot the clip ring of the front bearing ( under the throwout bearing shaft ), the input shaft was moving back and forward.
