mack88 Posted May 14, 2009 Share Posted May 14, 2009 I have A 1988 with a 350 12 speed . When it gets down to 30to20 outside temp it smokes white for about 5 min. before it clears up kind of misses to.The back out put shaft of the tranny was quite hot to touch after running down the road the other day.Any thoughts on what it might be? thanks.

Lmackattack Posted May 14, 2009 Share Posted May 14, 2009 normal for a cold engine to smoke on cold start in the colder months. Need to know how hot it really was. transmissions can reach 180 deg on hard long pulls. all depends if it has a cooler or not. lots of friction in those meshing gears. did you check the oil level?
