    Hi Guys,
    I have a 1995 Suburban K1500 w/5.7 T.B.I. It has one Oxygen Sensor.
    I want to find out exactly what O2 Sensor is the right one.
    I've been looking through some of the Auto Parts web sites, and my mechanic said to get a Denso or a Bosch.
    What I found was many of them said they wouldn't fit a vehicle with a 4L6OE Automatic Transmission.
    How do I know if I have that Transmission?
    Will the VIN tell me?
    My VIN is: 1GNFK16K6SJ312413.
    I'm hoping to pick this up tomorrow.

    Bob, Inside your Glove Box is a White Tag/Sticker....which is the Service Parts I.D. Tag(Shown Below)and on it you will see your Vehicles Vin # Number and a Series of Letter's and Number's which are RPO Codes.....which stands for Regular Production Options...In Short what your Suburban came with from the Factory......and your Suburban most likely has the 4L60E, and the RPO Code this Transmission is M30.

    The Service Parts Identification Label


    This is from A/C Delco's Online Parts Catalog, and it shows the following 02 Sensor for your Suburban,

    I would go with an AC delco sensor, you can get them cheap on amazon. I have seen some GM trucks not like the bosch O2 sensor, I would never buy a denso. I would also not buy a "universal" sensor where they come with a bunch of different connectors then you pick they one that fits your truck.

    I agree with Pikey on going with the A/C Delco 02 Sensor, as in some cases going with Factory/OEM Parts is the Way to go, and IMO this is one of those cases.

    they are $41 on amazon for the ac delco. ou also get free 2 day shipping if you have prime. If you have a .edu email address you can get prime free for 3 months and for $35 a year after that.

    I really appreciate all the input. I had planned on using the Denso Direct Fit that Advance Auto Parts has: http://shop.advanceautoparts.com/we...9-p?navigationPath=L1*14932|L2*16465|L3*16466

    I checked, and I do, in fact have the 4L60E Transmission. This one didn't have the designation saying that it wasn't compatible with it.
    I'll check Amazon and see about the AC Delco Part. This is something I'm replacing preventatively on a tune up, and darn sure don't wanna cause problems. I haven't paid for the other one yet.
    Thanks again,
