My 1992 GMC 1500 Winter Beater - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I just bought a real 'winter' beater. Can I detect from the VIN what tranny I have? 700R4 or 4L60? Thanks in advance.

Check the glove box and see if the option codes are still there. Otherwise I don't think the VIN will tell you. I have been wrong before but I think it was 93 or 94 before you had the 4L60E. I also believe there was a 4l60 (or 700R4) between the 2.

I believe the 4l60E code is M30

1970ChevC10 · 11-22-2020, 08:18 PM

Found it - now I just have to decode it. My M's are MD8 and MX0. Thanks a ton!

be a 700

1970ChevC10 · 11-22-2020, 09:29 PM

Thanks guys - the code yields '700R4/4L60' and someone else is saying (hopefully not fake news!) in 92 it was 700. When did they start the 4L60 - start of the 93 model year?

The 4L60 and the 700R4 are the exact same transmission. GM just renamed the 700R4. The 4L60E came out in 93 and is the electronic version but is essentially the same.

the MD8 was one year only. just before e series.i bought one in junkyard and put in my 72 c-10 cheyenne in 2017,works great.

1970ChevC10 · 12-29-2020, 10:03 PM

Onto my fuel lines - does anyone have a diagram they can share. Excluding the fill cap connections what are the 3 other ports (1) carb supply (2) return (3) charcoal canister? What is the 4th line that runs back along inside the frame?

I don't have a diagram handy but the fourth line is your rear brake line. It should go to a T above the axle on the drivers side and split to each wheel cylinder.

Thanks - once I pulled my bed up I figured it out, the PO had installed a new brake line and did not remove the old one. It terminates near the gas tank branch off (and out of site) from the bottom. Another landmine. Never a dull moment.

1970ChevC10 · 01-01-2021, 10:15 PM

Yes - just a different wrapper. My 92 has many similar features to my 70.

1970ChevC10 · 04-16-2021, 08:12 PM

Ok - have it saftied and on the road. I love having the 8' box and the ability drive and park it anywhere. It is so ugly nobody wants to borrow it or go with me. Peace and quiet at last!.

Trying to find a source for door sill plates, my junkyard visits have not been successful, I cannot remove any without damaging them. Anyone have a source? Rock? Classic?
