93 Nissan Altima Speedometer Trouble

I am trying to figure out what is wrong with my daughter's 93 Nissan Altima GXE. When driving, the speedometer jumps to 40 MPH and stays there and the transmission shifts "funny". It tachs up pretty high before shifting. Even putting in reverse and backing up causes the spedo to register around 40. I have replaced the speed sensor with no luck and just replaced the instrument cluster to no avail. Any ideas as to what the problem might be? Any help would be appreciated.

I just wanted to say that I have read your post and have no idea other than the troubleshooting procedure of replacing a suspected failing item with a known working item seems to work when all else fails.

The only reason I replied is because I do not see very much activity on this newsgroup at all. You will probably fix this problem way before anyone replies to this (if they do.)

Good luck!!

Must have been a bad Instrument Cluster. I just replaced with another one and it works. Thanks anyway!
