fixing old shitbox...simple mechanical advise needed!

[racsov500]

hey all

i recently got a old car for free from a neighbor. its a 1979 chrysler sigma gl. :aroused: you can stop laughing now. im not old enough for a licence, so this is a good oppertunity for me to practise driving and repairs. its good cause its plauged with problems, and i cant drive it properly until its fixed.

the biggest problem is the gearbox. (i have mentioned this in the thread about dead auto boxes)

start engine, put in drive. rev to get it to drive, and when it does it hop a little and grinds gears (ever heard a ride on mowers hydro-clutch?) car goes about 20meters, then stops. box dissconects, just like neutral. stop engine. wait for it to cool, then start again, sometimes it drives, but only for awhile. it shits itself on flats, so its got no hope on hills. unless its going down. i think its ripping itself apart, but everyone ive talked to says its fluid related. is this true? im going to take of the bottom plate and tighten the bands, and while im at it change the fluid. i havent really had a chance to check he fluid, i did when it was cold...on a slope and it was way over the top. any ideas?

there are several more problems, which i might post later. mostly brake and carby related.
