Do i need a transmission rebuild?? Well Do i?

Hey guys, as i mentioned in the other threads on here i just took my mustang out of storage and drove it for a few miles around town. I am having transmission issues and i actually had forgoten how bad they were.

here are the symptoms:

1.When driving normal car will shift thru all the gears no problem, however its is hard to put in because it doesnt wanna go willingly.

2.When getting on it the car will grind through every gear

3.When going in reverse up my driveway it makes a humming sound and smells like burned clutch 9 houses down from mine.

The Clutch is about 8k miles old and is a SPEC stage 1 clutch, the flywheel was also resurfaced at this time.

I was not the one that did this work however, the previous owner did it about 3 years ago.

The car shifted fine for a long time even when getting on it till i let my idiot friend drive it who thought it was ok to go from 4th gear at 50 mph to 2nd gear and punch it. ( im still slapping myself for that one)

So all insults and advice are welcome. Thank You all and have a wonderful day.

ohh can a mod please move this to tech. sorry

I dunno we will see, i am taking it in next week because i have a couple days off and hopefully its not raining, i need to get it up on the hoist and have the mech check it out. Also going to see how much its going to cost to swap in the pi cams because the intake i think i can do myself.
