The ’99 S10 ZR2 I’ve had for 5 years now has been pretty much bullet proof. Replacing the water pump is all I’ve had to do other than regular maintenance. But I may have forgot about the transmission. A trip to Charlotte, NC the first of this week I knew would be an interesting one, and it was. The reason was I had noticed some clicking noises coming from around the transfer case when shifting in and out of park, not to mention rapid clicking when accelerating. Of course I did not take it in to get looked at and I’m thinking now I should have. If something was going to go wrong I figured that was the time.

The trip was somewhat eventful on the way as the transmission would not shift down out of overdrive when coming to a hill. Once in Charlotte I had the transmission flushed at a Valvoline Oil change for $100.00. At least they did a flush and not just drain the pan and refill. That did help but there is still a problem. The clicking noises went away but now the humming came about.

A humming noise at about 55 mph seems to be what’s going on. When that happened to the wife’s car it was a bearing and a $1,200.00 bill. None the less the $100.00 at Valvoline was worth felling better about getting back to Nashville but the damage is done, I think.

I can only hope it is not a new trany that is needed.

Note: Gapping spark plugs correctly can also help with getting the most (power) out of ones engine. Check twice, gap once.
