    Speedo with trip odometer?

    So I need to narrow my search to a 88-89 suburban with trip odometer? That shouldn’t be hard to find!! The smart, quick, and easy thing to do would be to just get a replacement speedo that works and is quiet. What fun would that be??

    Speedo with trip odometer?

    I don’t normally drive my truck in the winter, but I needed to today. While the engine started instantly in the 8 degree weather, the rest of the truck wasn’t happy! Problem #1: the blower motor screams when it’s cold. Fortunately, that didn’t last long. Problem number 2: the speedometer...

    Power window stuck halfway

    You’re the exception to the rule. The same rule that says fuel pumps never fail when the tank is empty, only immediately after filling the tank.

    Power window stuck halfway

    Try some “Percussive Maintenance” otherwise known as giving the door panel a good hard smack. Sometimes the brushes in the motor stick, resulting in a less than ideal connection. If hitting the door fixes it, plan on replacing the motor soon. Power windows NEVER fail to open, they always fail...

    Delco 2700 ETR Cassette player.

    I listed 75, make an offer. As I mentioned, I’ll never use it.

    Delco 2700 ETR Cassette player.

    Well crap, for some reason I get a message saying the file is too large to post. If anyone is interested, I’ll email a short video of the radio playing.

    Delco 2700 ETR Cassette player.

    I finally got the plugs needed to test this radio. I removed it from my 81 GMC probably 25 years ago, as I suspected the cassette deck needs work. The radio plays, but the display and the sound comes and goes. I suspect it has more than a few bad solder joints. The tape deck will load, but not...

    TH400 trans service

    I don’t have a part number, but the shiny tan gaskets that comes with the TransStar overhaul kits work well. If the pan is flat and installed dry, it takes a rubber mallet the break the seal.

    Old school garage door opener remote

    Anybody in readerland have a junk old school large single button style garage door opener remote? I’m looking for one to install in my son’s 92 Yukon overhead console. My plan is to gut the remote with the exception of the activation switch, and extend wires from the switch to a remote to the...

    Transgo kit 1&2 vs SK 400

    Nick is a valuable asset to the transmission category of this forum. Lose the attitude and pay attention, you might learn something. I agree, if the transmission is out on the bench, I wouldn’t pay a dime for a shift kit in a 400. You can do the exact same thing (only better) during an...

    My 700r4 changes too early ?

    Before doing anything, make sure the throttle opens all the way from the drivers seat. Make sure linkage flex, floormats, or something else is preventing the throttle from opening all the way. Have a helper sit in the drivers seat, with the engine off (duh!) have him floor it while you look...

    Distributor with limiter

    I had one of the MSD ignition modules in my 455 powered 87 Cutlass, I was not impressed. While the car always ran, I always felt it didn’t run as well as it should have. My suspicions were confirmed when I sold the car to my brother in law, he promptly gutted it to basically turn it into a...

    No accessories power

    Do all the accessories work normally with the ignition key in run? If so, you can rule out fusible links and fuses and most of the wiring. More than likely, the ignition SWITCH (not the lock cylinder) is out of adjustment. The switch is located on top of the steering column. You will need to...

    Alt Replacement Options? A bit confused.

    The 78 and 94 amp internally regulated Delco alternators are cheap and easy to find. The 105 and 115 amp CS series alternators are just as common and almost as cheap. In my opinion, you would have to have a serious sound system or other equipment to need more charging system than 105 amps in...

    Advice on Transmission Fluid Change for 1980 C10

    Any GOOD engineer would design a product with routine maintenance in mind. A good engineer knows the importance of maintenance. Without a doubt, the bean counters vetoed the drain plug!! Bean counters play an important part in manufacturing, but I think they have way too much power.

    How many bolts hold the transmission on and where?

    If you’re absolutely sure all 6 bellhousing bolts are removed and the trans still won’t come off the back of the engine, more than likely the dowel pins are corroded in the trans bellhousing. Fisk them with penetrating oil and apply some heat. Work slowly so you don’t crack the case. You don’t...

    Advice on Transmission Fluid Change for 1980 C10

    Yes, your pan has a drain plug. HydraMatic stopped installing drain plugs in the early 70s as a cost cutting move, so more than likely the pan or transmission has been swapped. Possible leak spots: the transmission pan, dipstick tube or o-ring, kickdown cable seal, speedo cable seal, the oring...

    th400

    As long as it’s sealed up, I wouldn’t think it would rust.

    Rebuild th400 or 4l80e?

    Turn the piston upside down, see if it will fit over the pin. Or remove the sealing ring and try to install it. If it still won’t fit, its more than likely there is a burr or some other imperfection that is keeping the piston from fitting over the pin.

    Remove 4L60E

    If you drop and drain the pan, there will be very little fluid (if any) that will come out of the extension housing. Same thing with the cooler lines.

    350turbo out 700r4 in expected cost?

    What he said!! ^^^^ Too many people think as long as the tv cable is tight at WOT, then all is good. While that is partially true, it’s the other 95% of the throttle opening that will cause damage. If the cable is too lose at part throttle, then you will get mushy slip/slide type shifts. It...

    Alt Replacement Options? A bit confused.

    People run one wire alternators for one of 2 reasons: because they don’t understand how the charging system works, and are too stubborn to learn, or because they don’t understand the benefits of just repairing the system GM designed into their vehicles. Losing the remote voltage sense is one...

    A/C Question

    The A6 is VERY reliable, other than the front seal is designed to leak. As long as the have oil in them, they are just about indestructible. The A6 was so good, Harrison sold A/C components to ford, rolls Royce, jaguar, and a few other outside companies. The GM A/C systems of the late 50s to...

    Ac unit 84 cab.

    GM made millions of these trucks with A/C, I bet if your patient you can find a complete system. Ideally, find a system that is still charged and functional. When you swap the parts to your truck, replace every O-Ring, the orifice tube, evacuate and recharge.

    Please Help I'm Stuck!

    Cruise control on these later trucks like yours is a seperate add on harness. If I remember correctly, the cruise control module is clipped to a bracket near the gas pedal, the cruise servo bolts to the back of the intake, there is a connector that plugs into the speed sensor need the...
