    95 4L80 Low Line Pressure and No Line Rise under throttle

    Under load the amps should drop down to around .2-.4 amps, depending on how hard you're into the throttle will dictate how many amps it sends to drop pressure during a shift. When I get home I can try and find some TAP tables for a 4l80e to see what the PCM should be shooting for during shifts...

    Can I put a 4l80 transmission in my 1989 GMC 3500 5.7L ?

    Yes, I helped swap an 88 R3500 that came with a 5.7l from a th400 to a 4l80e a few years back for my neighbor. The hardest part for us was finding the right PCM for it and gauge cluster as I am beyond OCD about doing stuff so it can be worked on with common tools, and use off the shelf parts. So...

    95 4L80 Low Line Pressure and No Line Rise under throttle

    Is that commanded or actual? What were you seeing for amps to the EPC?

    4l80e and the differences between years

    If it was mine, I would not run a 91-93 trans. I know others do it, but there is quite a few mods that should be done to make a 91-93 trans work properly being controlled by an LS PCM or an aftermarket tcm. The 91-93 trans uses a different epc solenoid as well as a slightly different pressure...

    4l80e rebuild

    91-93 4x4's have BOTH speed sensors in the trans AND they used the one in the transfer case. 94+ omitted the output speed sensor in 4x4's, but you can add in the output reluctor wheel to put an output speed sensor in one. Most all of the internals between 93 & 95 interchange, but keep in mind to...

    Question on injector pop-pressure

    If you read deeper into those old posts about increased pop pressures, many people in summer experienced hard hot starts with pop pressures over 2500 psi. I wouldn't run more than 2300 on a ds4, especially one with any miles on it.

    Quick question for the ferminator

    Up to 96 has both cooler lines together, ALL 97+ have the outlet in the front, and the return near the rear. As Will pointed out, many people swap different years into different trucks. Functionally, 94+ all work the same, 95+ all have the bosses for the nsbu on the trans, so you could make it...

    Torque converter

    For that power level a triple disc is overkill. And there is no way I would put a $1500 converter in without going through the trans. Almost always if the converter is going, in a 6 speed, the C3 & C4 clutches will also be in rough shape(C2's are hit or miss with the 6 speeds). The LML...

    Condenser

    94, 96-02 are the same condenser, 95 is a 1 year only unit. The 95 condenser can be used in 94+, but the 94, 96-02 will not work in a 95. 95 has a m10x1.25 pressure port for a high pressure activated switch that forces the ac to recirc mode, 94 didn't use this switch, and in 96 they moved the...

    Torque converter

    How much power is he running? Suncoast has been getting some bad press here lately. That said, I'm still happy with my Precision Industries(of Tennessee). Goerand seems to be the go to right now. But without knowing power goals it is tough to say which converter. And is he building the trans or...

    95 4L80 Low Line Pressure and No Line Rise under throttle

    The blueing on the steels is from low line pressure. The clutch material is most likely from your converter. It sounds to me like you rebuilt your trans without finding out why your trans failed in the 1st place. Transmissions do fail, but the majority of them fail because something else takes...

    How do ya know if the fuel pump is dieing?

    That silver can on top of it that your fuel line connects to is the fuel filter/pressure regulator. You used to be able to buy them separately, but they cost almost as much as the whole module assembly. Found one...

    1997 GMC K1500. Knocking noise.

    Noises like this that come and go in the gen1 vortecs is normally lifters. It's hard to tell in your video though as that sounds like something else. Lifter noises are normally a hard metallic knock that come and go with oil pressure and rpm changes. I know my 99 has lifter problems, it will...

    best glowplugs for a 6.9 IDI with manual control

    I wouldn't run autolite's myself, heard of way to many swelling in the heads. And I looked up the 1115's, and I don't believe they will work with the stock glow plug system as they are 11V plugs. Beru(Motorcraft) only is what I was told for the International engines. And if you do away with the...

    95 4L80 Low Line Pressure and No Line Rise under throttle

    For the majority of people this is a bad idea. The radiator cooler is there for slow speed cooling, unless you have a trans cooler with it's own electric fan on a tstat switch, you will get overheating at low speeds. Gmt400 trucks have horrible airflow through the cooling stack, below 40 mph you...

    Torque converter

    First off you need to figure out which trans you have. A 93 1500 with a naturally aspirated diesel engine should have a 4l60e, not a 4l80e, and the 4l60e uses a 3 bolt torque converter, not a 6. Some 3l80/th400's used 6, but most of them were 3 bolts. The 4l80e used a 6 bolt converter, but only...

    4l80e and the differences between years

    I assumed he meant both were 2 wheel drive. Many people do not know C=4x2 and K=4x4, or think that C&K is a year difference. I really do not understand why so many want to swap transmissions instead of repairing there old one. Why put one in that could go at any time when you could have your...

    4l80e and the differences between years

    You would have to use your 93 valve body as the EPC solenoid is different as well as the accumulator housing.
