How to tell if my transmission is a 4L60-E

[Palmeroj]

Hi.

 

Vehicle: 1996 GMC K2500 Suburban 7.4 Lt.

VIN: 3GKGK26J4TG511185

 

I need to buy the oxygen sensors and my auto parts store is asking if I have a 4L60-E transmission.

 

Would be grateful if anyone could help me find out the type of automatic transmission in my truck. Based on the VIN, Is it a 4L60-E ?

 

Thank you.

Ask parts guy for pics of pan gaskets,take a knee,give a look under truck,or Google pan gaskets for 4l60e,4l80e

A 454 is going to run a 4L80e.

 

The weak 4L60e would have already died.

I was afraid to say,my luck it would be opposite of what I say,Soo many variables,the old" empty the parts bin "when changes happen,and rpo codes in glovebox will tell you,not vin

Pretty much anything 3/4 ton or 1 ton related always has the larger/beefier transmission.

 

Never seen a 4L60e installed in heavy duty frame.

Excellent information. I can see I have number 7.

 

Thanks!

I think there’s also deep vs shallow on at least one, don’t remember which. Seems like my

Haynes manual has some info. Or maybe lmctruck.com

Trans has nothing to do with O2 selection. It's a 7.4 that's all you need. The only thing that might come into play on the occasional vehicle,is the length of the wiring pigtails on the original O2s. Simple to measure if necessary

Right.  Simple to answer, a 454 (7.4L) will have a 4L80E.

 

And as you go one to say, the K2500 (3/4 ton) will have a 4L80E with either the 5.7 or 7.4.

 

Parts store guys ain't what they used to be.
