Transmission problem
1997 Other Chevrolet Models V8 Four Wheel Drive Automatic 198k miles

2 problems
1 the truck seems like its not shifting properly I have added fluid and I can see the level is good (while the truck is running after driving I checked again and nothing on the stick no visable leak completly dry underneath can't figure it out?

2 spedo tach not working as well as the PRND321 not visable (worked fine this morning) checked and replaced the fuse (#20 in the fuse cluster 10amp, says in the manual its associated with tach spedo auto transmission and PRND321) did not fix the problem
