The for what its worth auto repair and diagnostic thread.

[dudeman]

I've noticed there are a few of us on this board that have a pretty good knowledge of auto repair. I say we give back to the community. Ask away, I will do pretty much anything except go into an electronic automatic trans. Too many little things in them to go wrong.

I know enough to keep my ass on the road in -20° weather. You know a lot more than me.

I'm fixing to do a glow plug job on the 7.3 here soon. That's a pretty big job for me.

Automatics are for pussy's & rock climbers --

GPS suction cup fix --

When your cup wont such anymore -- release the suck leaver and run it under hot water for a few minutes --- then put it on the counter top and "Dont flip the leaver" - maybe repeat once or twice --

Viola -- you now have suck again --

Yep, that's the plan.

Good thread. My dad was a master mechanic. In fact, he was the one other mechanics called from competing shops, when they were stuck. I remember him answering the phone and asking a few questions then saying "check this, replace that."

I never thought I knew much compared to that, still don't

But compared to some of my friends, I feel like I know a little. Glad to help and very glad to ask for help when needed.

Before my legs gave out, I worked in a shop that got the vehicles that were at other shops and couldn't get fixed.

How about this-

89 Ford truck, 3 sp automatic, had the vacuum set up wrong after having the heads rebuilt. It would downshift when going up a hill, way too early. I thought it was the modulator, replaced it. Took it to the shop, they switched up the vacuum lines and it was fixed. Months later the map sensor went out so the truck kept dying. They replaced the sensor, alledgedly nothing else and now it's downshifting too early again. I wonder if the map sensor set new vacuum parameters or something? Should the modulator be adjusted? Since they didn't touch the lines i'm puzzled. I suppose avacuum leak could coincidently occured but that doesn't seem likely.

Did someone swap the trans? Being an 89, it should have an A4LD trans. Which is an electronic 4 speed. I'll need more info.


Is it a ranger or a full size with a C6? I still need all the specifics.

Definitely check for cracked vacuum lines and leaks.

It's an f250 Lariat, 5.8 liter, 4x4, c6 tranny. The previous owner may have swapped the trans, I don't know. He had cut and plugged lines that were probably for polution stuff. It doesn't want to shift until it warms up unless I back off the gas a little at the shift points. That makes me think vacuum too. I've spent far too much on this truck and don't want to take it in again. It sure looks nice though:-).

Start at the modulator and check the whole vacuum line all the way to where it connects to the vacuum source. Which should be the vacuum manifold mounted on the firewall. Also check the hose that feeds the manifold.

That sounds like a good start. Thx.

An engine needs three things to run. Fuel, spark and compression. We know you have fuel and compression.
