Need help! Noise coming from tranny!

supra kyle · 03-03-2011, 07:05 PM

bought a 1988 mk3 supra manaul a while back, was a great car far awhile but ive had nothing but problems with it. i thought it had devoloped rodknock a couple months ago so it sat around for awhile but i noticed that the bolt that holds on the crank pulley was missing. so i threw that on and it tottaly fixed it. drove it for about 15 min and now i hear a noise coming from the tranny. the best way to describe it is that it sounds like rodknock in the tranny lol. but right be4 this noise started my fan guard broke in half and took off a piece of the fan. im stilling picking chunks of plastic from the car. what is going on here?!?!? o and i drove the car for like 15 min 2day and the car was running perfect and then the noise started again...

Wow.... rod knock in a tranny... that's new. :P

I'd start with inspecting the drive shaft and the center carrier bearing in particular. Then I'd pull the inspection plate on the bell housing to have a look inside; If it's a W58 you're only option is to loosen the bell housing all the way around and pull the dust cover. Hopefully, it's the drive shaft or a shot damper in the clutch disc.
