    1998 6.5 2Dr Tahoe

    I will chime in with favor toward the 6.5. Although my experience is limited to my brother-in-law's 2500, the 6.5L was quite a good engine for him. No, it does not have the same torque as a Duramax. It was never intended to be a torque monster. It (and the 6.2L before it) were both intended...

    4L60E rebuild. What did I get myself into...? :P

    Hiram Gutierrez is the name I believe you are referring to. He is an absolute wizard with the 4L60e. His y-tube video is 2+ hours detailing a full rebuild. He talks through all of the decisions, and explains everything. I have rebuilt a few 4L60e transmissions, and I use Mr. Gutierrez' video...

    The VIN decoder says my truck has a 4L70 transmission, that's not right is it?

    With respect to the OP's original question, it should be easy to tell which transmission you have. The decoder says 4L70"E" (emphasis added on the "E"). If you have the 4L60, it would not have been electronic in 1992 (not a 4L60E, but just a 4L60). So the easy question is: does your throttle...

    Possible purchase

    I realize that market values are very dependent on where you are in the country. I live on the opposite coast, but $3000 for that truck is a good price here. Notice that it doesn't show ANY rust. Typical of So Cal; typical of SE NC where I live too. The interior looks good, and I wouldn't...

    Carb SBC vs TBI SBC vs Gen 3 LS reliability

    I'll throw in on this. My vote is TBI for its simplicity. If you can trouble shoot a carbed 350, it's a short learning curve to handle the TBI 5.7. And the actual throttle body injection unit that gives us the initials "TBI" is far simpler to work on than a Q-jet. It IS plug and play...

    AC Rebuild Input please-condenser yes or no

    Wouldn't dream of it! I was just noting the big ticket items.

    700r4 all neutrals.

    I believe you are correct. I'm looking at my photos from my last rebuild. Here's a thought. The parking pawl is engaged by the same rod/lever combination (inside the transmission case) that actuates shifting the transmission into drive or reverse. What if that mechanism has somehow become...

    AC Rebuild Input please-condenser yes or no

    With all of the other items, you might as well do the condenser. Remember, it's probably the same age as the compressor. I have to do my AC system soon. I'm doing compressor, drier, condenser, and probably evap core. It's an '88 model, so I'll have all new items for reliability. That's my...

    4l80e install question

    It won't matter what position it's in on the install. Once everything is in, you will want to make sure that the shifter correctly shifts to each gear without binding and that the detents line up with your factory gear indicator on the dash. It's typically adjustable, but I'm not up-close...

    4l60e rebuild price

    For what it's worth, rebuilding an automatic transmission is a skill. Skills can be learned and refined. If you have the luxury of this not being your only driver and you have good mechanical skills, why not give it a go yourself? Every expert transmission rebuilder rebuilt his first...

    PRNDL switch

    Just out of curiosity - if you had a carburetor, what would you need a TPS sensor for?

    1990.. Been parked 2 yrs... No fuel to Tbi..Tia

    Well, I found my way all the way to page three, and I was about to suggest what Vettepilot suggested. This is the EASY was to check throttle body injectors on this truck. I went through a similar scenario with my 1988 SBSC 4WD. Sat for 10 years before I brought it back to life. Try the 9V...

    Installing bucket seats in a 1990

    It would depend a bit on whether you are in a snow/salt prone area. Where I live we see snow about once every four to six years. Salt is what we put on popcorn. Any rust here is from a vehicle that "immigrated" here from elsewhere. I installed factory buckets from a 1994 ECSB in my 1988 SCSB...

    The Stupid Electronics Questions Thread

    No, the switches are not interchangeable without changing out the switch housing panel, and those panels don't fit the opening in your current door panel.

    Help please

    IF there is enough of your old harness left to compare, check to see if the connectors on the donor harness match the connectors on your harness. Another way to check is to see if your transfer case is the same model as that from a 2500. I'm not sufficiently knowledgeable of transfer cases to...

    Why are expensive hand tools better than cheaper ones?

    I'm in agreement with Mr. Yukon. It seems as though much of this discussion is Snap-On / financed tool truck tools or Harbor Freight. When it comes to hand tools, I buy Craftsman, Kobalt, or the like. I'm not a career mechanic, but I am what you might call an extreme DIYer. It means that I...

    4 pinion planet BETTER than 5 pinion planet?

    Not to come across as argumentative, but while both of those modifications will change the way the vehicle performs, neither will affect the relatively larger gap between 1st and 2nd (larger, that is, than a TH350 or TH400). Changing either is external to the transmission, so the gap remains...

    LS swap 4l60

    A 4L60 non-E doesn't use a transmission controller. (The 4L60 in non-electronic configuration and a 700R4 are the same thing. GM updated its part number from the old TH designation to the current alpha numeric format early in the GMT 400 production.) A 4L60 non-E does employ a controller for...

    DOOR ROD DIAGRAM

    I agree with Richard. If the release lever on the door latch is pressed down, the door opens. The only reason it wouldn't is if the latch is locked or suddenly broken, but broken usually happens over time. It's pretty tough to knock it out all at once. Can you reach inside the door shell and...

    Rally Wheels

    I put a set of 6 lug 15x8 wheels from a 1980 K10 on my 1988 K1500. I kept noticing a faint squeak/chirp when I had my windows down. I pulled the front wheels and noticed witness marks on the inside of the wheel and one corner of my caliper. I was more comfortable grinding down a corner of a...

    Paint Match Question

    I wouldn't bother painting anything with a spray can, if that's what I understood you to mean. It will not last. Not even for a couple of months. If you want to do it right, drive your truck to an auto body supply shop. They can use a hand-held gadget to determine the correct color mix...

    Restoring RWAL

    Steven, thank you for this write-up. My 1988 RCSB K1500 will lock the rear wheels if I need to stop quickly. The RWAL is inoperative, and I have been searching for information regarding restoring it. Almost everything I read is about deleting it. It seems that few are willing to fix the...

    No start TBI - fuel pressure drops to zero after priming

    No. It's internal in the throttle body unit, not a self contained regulator like some vehicles have. Desert Old Guy, I missed the mention of the 12 psi. That would indeed eliminate the regulator as a culprit.

    Cracked 5.7 block at Starter Bolts

    +1 on welding the stud and the fracture. Just be sure to run the stud in all the way, and then grind the crack all the way down and weld it back. It will be stronger that way.

    No start TBI - fuel pressure drops to zero after priming

    You might also consider two things. One is that the fuel pressure regulator may have failed. It is just a rubber diaphragm and spring in the throttle body. The throttle body itself may look intimidating (or it may not, depending on your DIY-ness) but it's simpler than a Holley (I prefer...
