My turbo 350 transmission is leaking?

front seal......or rear seal......or pan gasket.......or dipstick gasket.......or selector shaft gasket......or speedometer drive seal............or cooler lines.........or internal issues to great that it's blowing fluid out the dipstick.

if it's leaked enough to make strange sounds, chances are good for internal damage.

What she ^ said. Stop driving the car.

If you want to see where it's leaking from:

1. park it, start the engine and let it idle warm, with your foot on the brake and parking brake engaged and no one in front or behind you move your shift lever from park to drive-n-reverse and back and listen to the sounds.

2. Turn off the car and look underneath

It may be something as simple as pan gasket leak and worn out mounts.

i don't be attentive to exactly what the first answerer develop into quite speaking about yet once you want to fix the concern do this. Take off the belts, water pump, etc. until eventually you would possibly want to get the timing chain conceal off. be careful prying it off there on the grounds that you do not prefer to bend it up too a lot diverse wise it gained't get a bodily efficient seal once you position interior the diverse gasket. at an similar time as you've the timing conceal off there look into the tooth on your timing chain kit. If it had the unique timing chain on it and hasn't been replaced seeing that seventy 2 you'll word that they used plastic tooth on the gears. Line up the timing marks from the crank kit and the camshaft kit on your timing chain and use a puller to drag it off and reinstall a clean one. in case you basically prefer to seal up the timing chain conceal then move to the parts save and get a gasket for it and placed a smooth coating of silicone round both aspects of the gasket and opposite the technique. be confident to bathe off your previous gasket solid first of coarse interior the previous installation the hot one. also a bodily efficient rule of thumb is to modify your oil once you're trying this through actuality debris and antifreeze receives into your oil pan at an similar time as your doing all of this and that is not solid. choose this helped you out and shed a contact comfortable on the undertaking.

the *trans* is making the knocking sound? a th350?

@ idle too? in neutral?

i'd check the engine crank main pulley for walking in and out. may have a runout issue with your crank.

only under a load?

i'd check the u-joints. maybe an engine/trans mount issue. causing exhaust knocking on surrounding parts. check exhaust hangers and such.

and where is your trans leak coming from? prolly unrelated unless it's a trans front main verter seal.
