I own a 1998 Jeep Grand Cherokee Limited 5.9L with 127K miles on it. I changed my tranny fluid about 4K miles ago. Recently, I went to a football game and I was in traffic for 2 hours. As I was nearing the stadium the traffic started moving. The tranny was winding out going into 3rd gear or overdrive and it didn't click into the next gear until I was going about 50. This has happened about 2 or 3 times since after I have driven lets say 30 miles on the highway and I take an exit and the tranny has to start shifting again. When the car is cold it shifts like a champ. I had my mechanic look at it and he told me there was a leak between the transfer case and the tranny, the gasket has to be replace to the tune of $350.00. I have had to put in fluid a couple times since the fluid change. The question I have is am I wasting my money here if I make this repair. Does anybody have an experience similar to this? I don't want to spend $350.00 now and then in 3 months have to do a bigger job also. Is this $350.00 repair worth it or is the tranny on the way out and I should live with it until it gets so bad I have to replace the whole thing? Any advise would be appreciated. Thanks.
