Shifts hard like a clunk. i think it a adjustmant

check ur cv axles one may be going bad also check steering and suspension system--struts worn, loose --ball joints goin --even tie rods can cause play

check the actuator vacuum/ wires for operation as it sounds like the actuation is not completing the movement properly for the front hubs.

Stop using it

If have been, you may have ruined it,
just driving ten miles

Have a trans shop diagnose the issues

The clunk into reverse troubles me alot

I used to own a trans shop

There is an adjustmant but that is not the problem.The problem is the two bolts that hold the shift cable bracket to the steering column.They are #30 torqx and a little hard to get to, you will need to get under the dash and wiggle the shifter to identify the shift cable and baracket.Tighten the two bolts and all should be good.

Check your transmission fluid level when the engine is running and the car is in 'park'. add extra appropriate fluid as necessary via the dipstick tube. When 'max' is reached I think you will notice a return to normal shift operation.

start be looking for broken motor mounts if there broken this can happen look for rips and tares in the rubber in side the mounts you may need to put the car in the air to check the rear mount. if you find one that is broken replace it and see if that solves your clunk.

It has nothing to do with the transmission, it's your engine mount thats bad.

Check motor mounts.

check the brake dust shield beind the rotor. That might be a good start. Not sure what you mean by clunking but also check your engine mounts bushing and sway bar bushing. Good luck

when the last time you made a tranny oil change ? or also check the level of oil when all that is done youncan get more technical lets see could be the shift bushing ... easy to install and if its a tranny probleme well maybe time to get that corvette you always wanted go big or go home ahahah good luck
