Registry 8x Series V8 Swaps

I guess is that you run the L-R (ground) to the black wire (ground) on the trinary switch. This looks right?

If your asking me I didn't use a trinary switch.

Was gonna tell you to just put a new gm starter on it but let you figure that out on your own. When you pulled the starter out did you shake it like a shake weight and if you did did it sound like something major loose inside of it .?
On your shifting who did the tune? At what rpm are you letting off the throttle at? My tune guy sets it at 6500 rpm at wot that means if you have it floored it will not shift until 6500 rpm you have a 4l80e in your swap ? If so first is long so waiting on 6500 rpm and then to let it hit second is a little scary my tune guy said this to me it shifts as per throttle pedal so if you give it the beans that's what your gonna get. Other than that its the only help I have for ya.

I’m still running the stick tune from Speartech. I was told it’s a factory tune with all the stuff out it to make it work for the swap. And deleted the O2 sensors. I haven’t taken it I a tuner yet because it’s been running so well so far.

Maybe it is holding it until it reaches that RPM. It holds 2nd too. Not just 1st. And I don’t know the exact RPM because my tach doesn’t read accurate on the dash. I need to hook up a scan tool with live data and drive it.


Also, no the starter didn’t rattle. It just had a burnt spot on the solenoid from heat from my exhaust manifold. So I bought a heat blanket for it from Michigan Motorsports to help my gm starter last longer.

Maybe you should get an ultra gauge? @FlyinFaded. So many features. Hottest I got on the trans tempt is at 140 F driving up the mountains.

Oh man. This explains it. I hope this is the problem to the P2135 code. Pedal sensors 9 pin. The tac module harness I got off eBay (2002-03) has 6 wires. Should be 9.

My ac condenser fan is turned on automatically by the stock pressure sensor located in front of driver side battery. When pressure hits I forget what pressure it turns on the fan. Here is the thread for it

Part I - The Need for Aux Cooling

Now that Chicago is hitting 100, figured it might be a good time to put some data and thought into our 80’s issues of (over)heat. Since we don’t have a lot of data in regards to things like our Toyota Engine driven Thermo/Fan CFM, RPM and other factors that will help us determine the best cooling method for our trucks, maybe we can look at some of the things we do know about 134a and our A/C systems. For the purpose of discussions of 80 over/heat, I will only address the high pressure side of the A/C system, as it is what creates the heat in...

That thread needed lest talk and more pictures lol

Here are more pics @ Tommy. Removed the ac compressor took about 10 mins. Love how simple these engines are. No oil spilled out of the drain or check bolt. Overheat for sure. I’m replacing the drier. Need to figure a way to flush out the system; didn’t see any metal shavings. I only used the ac for like a few days of driving.

True, but it shows how to use a 14 inch fan instead of the smaller factory fan. When I did this 20 years ago you could still get the factory pigtail for the pressure sensor.

It’s ridiculous how much people ask for the drier for a used on on eBay when you can buy a genuine gm one for $20. Looks like this is compatible for our 80s, check out rockauto.
