So far it shifts smooth seems to accelerate stronger but twice it started chugging then died no check engine light almost like fuel starved. First time it restarted right away second it had to sit for about ten min then started right up both times it had been running on the highway 60-70 mph for at least 30 min I changed fuel filter about 5 months ago unsure what it is never had done this before. Shop said it had not done it to them and did not think it tranny related. alternator putting out 14 volts at idle battery about 12.5- 13 motor off .?
