I have a 2005 TC with 159,000 on the clock. Considering transmission service.. The service interval per the dealer is 3 years or 60,000 miles. This March I hit the 3 year period, but I only have 38,000 since the last service. Most of my driving is long distance road trips, maybe 80% plus. Does anyone see any reason I can't wait another year of two until I am closer to the 60,000 mile mark?
