What does the pan on the 4L80E tranny look like?

[afroman006]

I found a 91 3/4 ton Sub somewhat near me and the owner doesnt know anything about it. Questioning him on the phone, I could not find out what the GVWR of the truck is. I asked him to go look for the sticker on the inside of the door and he did and said there was no sticker /forums/images/graemlins/rolleyes.gif. My question is this, is there any other way to tell if the Burb has the 8600 pound GVWR? What does the pan on the 4L80E look like? Is there any other way to tell? The VIN? He said it has an auto tranny with overdrive and the towing package. I would just go look at it but its about a 2 1/2 hour drive away. Thx

i don't think gm had the 4l80e in 91. and if he is the original owner it doesn't sound like he would put a 4l80e in that. i would think that it has the 700r4.

Yes, that should be the 4L80e.

Pan looks like:

At least on the later ones, "4L80E" is cast right into the side of the tranny.

Maybe someone thats looked at a '91 4L80E can comment on that.

Easy to see on some of the vehicles they are installed in (van based panel trucks, etc) but in a truck, maybe not too easy to see. Passenger side, right around where the bellhousing "bulge" meets the case.

'91 was the first year the 4l80e was available in suburbans.

It also is the ONLY chevy trany with 17 bolts holding the cover on. Ask him how many lugs are on the wheels. Obviously if it's a 3/4 ton and its a 1991 and its an overdrive it will be the 4L80E. Ask him what the tansmission selector has on it ie does it have an overdrive position.
