Default Re: '66 1500 slipping out of second gear

Merry Christmas folks, thank you for the I formation, I even know what a sm318 is now lol. I do believe it is a worn gear. It goes into gear just fine with no grinding, and if I baby it, it may stay in second but will feel the spot that is worn. Under load it has no chance of staying in gear. Brings me to my next question...where might I find a second gear for a sm420 4 sp, and any idea what it will set me back? So far I've been blessed and very fortunate in costs for parts. While not original the 350 v8 previous owner put in is in great shape. The only issue needing immediate attention other than tyranny is the heater fan screams like a banshee when first turned on. Took it out cleaned and oiled/wd40'ed and put back in...maybe time for a new one... thanks again for I fo and help.
Dave
