There is an interlock that locks the shifter in PARK when the key is in LOCK. You can't get the key into LOCK unless the shifter is in PARK, and you can't get the shifter out of PARK unless the key is not in LOCK. It's a mechanical cable between the shifter and the ignition switch on top of the...

I'll generally only work on bone-stock SyTy in unmolested original configuration. No headers, no turbo-tweak chips, no air to air intercoolers. If they can't pass smog because of the mods, I'm not interested. The smoke on hot restart is valve stem seals. Blower motor inop can't be too...

Is it the same #1985? There are two #1985. A 92 and a 93. From the description in the opening post, made in 2005 (16 years ago) of "rust so bad the cladding has to be taped on, and holes through rust with a screwdriver" I'm skeptical that such a rotted mess would still be around in 2021. Could...

$75,000! I'd like to know if this "sale" actually gets funded and happens. I'm sure the seller is ecstatic, but it isn't a done deal until he gets the funds in his account.

Withdrawing money to a bank card It is convenient to use Visa, Mastercad or Maestro cards. They are used to pay in stores, make purchases on the Internet. To transfer funds, go to <a href="https://mine-exchenge.org/" title="mine exchanger"> mine exchanger </a> and select the exchange direction...

It's the pick-up coil inside the distributor. Has a green and white wire that plugs into the ignition module. Requires removal and dissassembly of the distributor to replace it. About a $25 part.

Many people will disagree with me. I've seen claims of 20-24 MPG. Bull Shit. My experience with 4 bone-stock, including the "chip" SyTy is they get 16.5 on the highway, and about 10 around town. Sometimes less.

4 minutes of video and I didn't catch a single up-shift. Couldn't hear one, see one on the speedo/tach, nor did either occupant count out the shifts audibly. 800 RPM change for lock-up? Wow, stock is 200 RPM. An 800 RPM drop no longer controlled by the ECM is going to be tough to live with. He...

Just for grins, with the truck in normal attitude (level) remove the T-case FILL plug and see how much comes out. There may be a lot, so put a pan under it just in case there is. If the level is high, the input seal has deteriorated, and ATF from the transmission is migrating into the T-case...

Was the engine running when checking in Park? (It must be.) Get your fluid level sorted before you do anymore WOT testing. These trucks shift so violently that a low level can result in slipping damage. The TV cable probably needs to go outer-jacket to the right. (Inner cable exposure becomes...

Some people disconnect the temp cable to remove the A/C control panel completely. Back in the day, I did too, and I struggled and cursed, and broke some controls. I finally adopted a "better way" in that at least it is faster, and less prone to frustration and broken plastic. Remove the two...

I've been around here since 1998. Peeps that know me know that I am always serious. Yes and Yes. I do my own 4L60 and 4L60e. I've helped a couple of local peeps with their transmissions too. Some come out well, some not so well. Same results as professional builders. There's a lot to go wrong...

That guy is an idiot. He doesn't have a clue, "and stuff like that"............ I got so tired of his BS and wrong info I quit watching his shit after about 5 videos. I just tried to watch this one, and he's so wrong, so fucked up, I just turned him off. More power to him, he has a following on...

Who went? How was it? How many trucks in Building Y? Thanks

Gadzooks. Steve Gavic checks-in. You've been around a long time too. Do you still have your Typhoon? (Probably). I still have one of each, my Ty is still bone stock (but of course) and has a gillion miles on it, but is still capable of a cross-country trip with the hood welded shut. There...

That wad of tape is covering the diode in the purple wire which is power to the TCC solenoid when the brake is NOT applied, with the key in RUN. The location of the diode is in the engine harness about half-way between the bulkhead connector and the branch-out down to the transmission.

All GM automatic transmissions were "re-named" in 1990 to more accurately reflect their attributes and torque capacity. The 700R4 became the 4L60. The "MD8" is the RPO for the 700R4 and the 4L60. The MD8 used in the SyTy and other trucks is the "K" case that has a bolt on aluminum cover and...

The fueling remains at what it is for 14.7psi. There are no additional fuel cells above 14.7psi. If the Air/Fuel ratio is correct at 14.7 (max 2BAR) the A/F will become lean at higher than 14.7 as the volume of air increases. Lean mixtures tend to detonate, and blow shit up.

Do not adjust the Throttle Valve cable in an attempt to change shift quality or timing. You can F-up your transmission. The TV system in the 4L60 (in 1990, the transmission became the 4L60, it was no longer a "700R4") is critical to establishing the correct pressure at the correct throttle...

MSD = May Suddenly Die Does the tach indicate cranking RPM when cranking? If = No, the distributor may not be sending pulses. I like this little test for distributor pick-up coil heath: Turn key to RUN, do not crank. Leave key in RUN. Fuel pump should run for 2-3 seconds and stop. If=YES...
