Think maxtronix is right about your car info.
For your transmission I cannot tell you exact what is wrong with it, but I tell you to
check 3 things that cause jolt in gears, 1- check your gearbox suspension, 2- check
your propeller shaft, it hasn't to be shimmy, 3- check your disk for each gear
These three issues cannot be identified via diagnostic tool, it's experimental
Good luck
