I noticed a couple of weeks ago that that the TC was delayed in locking up. I notice yesterday that now it may not be locking up at all. I had a TC and VB from DTT installed about 150K miles ago and had to replace the lock-up valve clip about 25k ago. Any thoughts or suggestions on trouble shooting the problem? Haven't pulled the pan yet. Unfortunately, I have a car port to work in and it's been a little chilly around here lately. Happy Holidays to everyone.
