this may be a long post, but i am a young 02 owner and i need your help guys and gals. so i just got my 74 back from the transmission shop and i took it out for a drive and i noticed a few things that are keeping me awake. (its 2 am)

1) while revving in neutral i sometimes get a very scary whine or grind sound coming from the engine. it sounds like one of those dying rabbit/animal whistles....????

2) when in first gear, i was driving very slowly (no more than 10 mph) i felt and herd a bunch of thudding from the rear end or maybe the tranny.....?

3) when starting the car, it turns over, but cant stay idle. i have to turn the key and then tap on the gas a couple times till it gets going. is that normal?

ANY help would be amazing. thanks guys and gals.

1. probably some bearings, need a rebuild.

2. could be suspension, more likely than tranny

3. carby could be out of tune, plugs could be old, ignition could be off. That sorta thing is more of a tuning thing, could be looped in with question one though.

why was it at the transmission shop in the first place? is it a manual or an automatic?

not sure what the grinding is, but maybe the whining is your fan belt is slipping and it's making noise? it only happens when you rev it? check to see if it's worn or loose. maybe there's a bad bearing in your alternator?

thudding could be transmission, could also be a broken differential mount?

do you have the original carburetor? no manual choke, right? when starting from cold, try pumping the gas pedal all the way down to the floor ONCE before turning the key. don't touch the pedal when turning the key. starting procedure is different if the engine is already warm. if you have the original owners manual it actually tells you this stuff in there.

Thumping? Loose bolts attaching the driveshaft to the trans or diff.? Did the shop have the transmission out?

The high-pitched noise might also be something rubbing on sheetmetal, like the flywheel against the dust cover on the front lower edge of the trans.

k thanks for the answers so far. the reason why i had it at the transmission shop was because i needed a new clutch and a bunch of other stuff:

sachs clutch kit

throwout bearing

5th gear bearing

trans seal output

trans input seal

trans shifter seal

thrust kit

machined flywheel

ill check the belt, but i think thats fine because i put on a new water pump, hoses, t-stat, hoses and belt, but ill go check now.
