I was totally hoping this would be the power steering or something like that but the sound is definitely coming from the rear of the motor by the tranny. Im going to go down there now and mess with it.

4L80E swap time!!
would the 4L80 bolt right in or do I have to do other supporting mods?

I've read the 4l80 is actually the evolution of the th400 and it's not a version of the 700r/4l60?

Highest chevy stock converter for stall speed is from a 86 vette. They dont make them anymore but from what I understand, one from a S-10, v6 truck is the same unit.

correct and in a vette usually was an upgrade felt like a 2800 stall.

I am thinking it might not be trans related, can't wait to hear what it was.

It bolts right up to the engine block... the back of the trans is a different story. Need to find a way to mount it to the C-Beam, i created my own adapter.

I did this mod to my car, and it is by far my favorite one. The gear spacing on the 80e is awesome. 1st to 2nd gear RPM drop is not as bad as the 700R4. In my car with the gear/tire/RPM, 1st gear is good for about 60 and 2nd 110 MPH. Coupled with a 3200 stall it has been an absolute ton of fun to drive

So I did this last night.. and im not that lucky it seems.. Sound was still there and def coming from behind the motor. Im going to drop it off at the transmission shop as soon as I find the time away from work to work the logistics.

Dam that sucks, sorry man

I would also at least pull the dip stick and wipe it clean with a white rag. See if there's anything suspect in the fluid.

hey.. comes with the territory of owning an old chevy! Whats funny is i always stayed away from automatic sports cars bc "you dont have to worry about blowing the tranny!"..lol

So i just did this and i cant say its all the way clean.. there seems to be the slightest amount of metal on the paper towl i used to wipe the dipstick.. and the fluid looks a little more red than normal.. if that makes any sense.

Any car.can blow a transmission whether it is auto or stick. I've seen broken sticks too.

Drop the pan

I loved my 93 ruby, but I sold it to get a zf6 car. And yeah the trans went out years ago on the ruby, so I know what you mean and feel.

And yes, aklim is right.

Aklim is right but it's different in my experience. All the manual cars I've owned or been around could generally take more race type abuse then their automatic counterparts in stock form. Everyone knows you can certainly build a nice rebuilt robust automatic transmission and is probably better way to go when drag racing. But I'm always a little worried to drive stock automatic cars hard.. always waiting for that slip or in my recent experience a fckin explosion.. never had a stick blow up on me.. just sayin. I know manual trannys can "break" but as far as I'm concerned that's way different than how autos go.

Completely agree as well. Sorry to go off topic. My dad had vettes, many while I was growing up. I'd say each and every car was headers and cam. The few auto vettes he had blew the automatics pretty quickly. The stick cars indeed lasted longer. He bought a C7 GS back in May. Stick as well

I think back in the day, it was so since auto transmissions were newer. I think over the years, they have become better, like anything else.

Agree with you here too.. But, you would think you would see more 8l90 swaps. doesnt seem like many are doing that.

Mine started making a terrible noise last month and my torque converter bolts came loose at once. Sounded like I blew the transmission or engine. The transmission shop tightened them and it was better than ever. Good Luck
