I've got a customer that wants me to service the transmission in his truck - would like to go with a syn if possible as he complains of tough shifting the first few miles in the winter, but locally available GL4 oils are a bit tricky to come by. What options do I have? Will oils like syncromesh or other dedicated M/T oils work in this?
