Question about 1992 Chevrolet C1500
I have a 1992 Chev Silverado. I would like to know how to tell from the vehicle vin code what transmission is in it? I just purchased a 1992 truck and was told by a 3rd party that the 2nd party changed the engine, but I am not for sure. How do I tell the size of the enine and tranny?
I can tell you what engine is suppose to be in it by the VIN. I can tell you what transmission you have if you can describe the shape of the bottom pan. As far as the engine that you have that is tough. The engine size should be stamped on the rear of the engine near the distributor near where the engine and transmission meet. Rectangular pan 4 speed= 700r4 Pan like the state of Illinois, 3 speed= TH400 Squared off in front, tapers on both sides to the rear and slopes up to the rear, 4 speed=4L80E These are the only transmissions that were factory installed in a 1992 C1500. If it looks different let me know. You never know what someone has installed.

Tenth position of vin tells year of vehicle, for 1992 should be N. 8th position of vin tells engine that it left assembly plant with. they are:Z 4.3 liter V6
H 5.0 liter V8
K 5.7 liter V8
C or J 6.2 liter diesel
F P or S 6.5 liter diesel
N 7.4 liter V8 (454)
as far as the transmission goes not sure, some of these trucks had turbohydramatic 400 and of course there would be different (heavier) torque converter in diesels.
