Tranny Problems

[H2Pilot]

I have seen other posts on here concerning transmission /shifting /power problems, but the newest ones are from 2003 So I'm gonna start something new.

Prob 1: Last week we had the 30k mile service done and afterward the speedo started getting stuck. I pulled the fuse and replaced it and it works OK now but not perfectly. It kind of ticks down now like the second hand on a writswatch. ==REPLACING INSTRUMENT CLUSTER==

Prob 2: Three days after service we drove from Los Alamos, NM to the Grand Canyon. Great trip except the tranny started acting up and seemed to disengage or slip and allow the engine to revup quickly to 5k-6k rpm. Also, when I was going about 70MPH, it seemed that the RPMS were a bit high and I thought maybe it wasn't going into 4th gear or overdrive. So I tried moving the shifter into 3 to see if I was right and there was absolutely no change in the RPM -- stuck in 3rd gear with 300 miles left of driving!

I live up on a mountain, and on the way home it was slipping so bad that I thought I wouldn't make it up the mountain. ==GOING TO DEALERSHIP TOMORROW==

The reason I am posting this is to see if anyone here thinks these two problems might be related (all electrical /computer problems) and to get a little insight before I get to the dealer in the morning.

Thanks,
Tom
