Can anyone confirm if the label on my memcal prom is the right stock prom for my 95 Tahoe 4X4 5.7L? I don't know if this is a stock number or a modified prom.

 

The label on my prom looks like this:

 

5158

1617

4895

 

limp home board has a part number 1265153

 

stamped on the memcal cover is BJYL 0099.

 

VIN # is 3GNEK18K3SG107271

 

Gear ratio GT4 G80 3:73

 

Any help greatly appreciated.

 

thnx,

gnuman

I thought I might have heard something by now by a seasoned GM tech. Maybe this OBD1 stuff is too old school.

 

Has anyone upgraded or replaced a memcal prom as part of a GM service routine? If so, what kind of labelling do you put on the prom?

 

thnx,

Wow, one whole week and not one reply. I'm a bit disappointed, as I had expected experienced GM techs to have been all over this. Not even a yes or no. Not even a "you suck" or "take a hike". Must have been a tough question.

 

Maybe one of the techs can answer this one:

 

When I move the stick that is connected to the right side of my steering column clockwise, it moves a little red needle on my instrument panel to the right. If I start the engine, release the emergency brake, and the little red needle is pointing at the "D" on my instrument panel, can one of the GM techs tell me which way I can expect my truck to roll?

You suck and go take a hike. :lol:

 

Probably best to go to a dealer and have them look up the info

 

Being a smart ass with your question won't help you.

You're welcome,and good luck with your quest :thumbs: Even though by today's technology standards OBDI systems may be dinosaurs they can still be modified to improve performance.

      Wiring Help, Please

      Thanks; I looked there a few minutes, and I think I can find something. I really never looked there, as I thought it was stuff like PTO/aftermarket bodies/accessories like snow plows.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
