I just got my late 1994 XJ40 back on the road after a few months being layed up and when I went to drive it back from my shop I noticed it wasn’t shifting into top gear and the transmission warning indicator on the dash was illuminated. I have see other folks mention cleaning the contacts int the TPS curring the warning lamp problem but I don’t know if that same “solution” also applies to the won’t shift problem too.

Any hints or suggestions would be most welcome since I would like to make this car my daily driver again.
