​@RainmanRaysRepairs hi Ray, love your content. I'm joining the industry this year. You've been a big help and big inspiration doing some backyard mechanic work

Great bit of O2 debug correcting the confusion of the mis plugged connectors....confusion defeated !

[@surferdude4487]

Not only did the transmission shop mess up the sensors and fail to replace the rear main seal, they also let that shifter go out of their shop in that condition. ZERO pride in workmanship.

[@KaiSyversen]

I am both perplex, and not surprised at all. On how much trouble one mechanic can create and/or ignore when doing one job, that they leave for the next person. Its like that meme with the roadkill and roadpaint going over, it stating: Its not my job.

[@terrywebb8636]

Hey Ray, it's just amazing how with a little time and effort a good mechanic can work wanders, yes you were right the transmission installer should have replaced the rear main oil seal, but they didn't, we need more mechanics like you, see you next video.

[@livetillyoudielovelife2299]

It could be that the owner would not pay for it

Ray ,this is what happens when you don’t have emission inspection or safety inspection (no catilytic converters ). Maybe it get better fuel mileage with deleted cats. Anyway you fixed the rough running condition. Have a good day Ray

[@GReaper]

Side note, if the PCM sees a problem with any of the upstream HO2 sensors, it'll fallback into two possible modes. Open loop, where the entire engine runs in open loop (depends on engine and PCM), or what some readers may refer to as Faulted mode (i'm calling it this because this is what I saw it as in my scanner software I use). In this latter mode, one side of the engine will run in closed loop, but the side with the defective sensor will run in open loop. Depending on the PCM and the scan tool, this fault mode may simply show as being in open loop. Either way, the PCM may occasionally check to see if the sensors may have happened to start acting right and attempt use it again unless the fault persists.

[@vc8939]

Good evening Ray, Always impressed with your diagnostic skills and knowledge. Where are my Dave sightings the past few videos??? Gravity.

[@oldbiker9739]

good diag Ray , I need to pull the trans on my 91 GMC 1500 ,and thanks for the heads up to do the rear seal as well it does make sense its got 240,000 on it .

[@jthonn]

Anytime you do a big job like that and have everything pulled apart, you change anything that you can while you are in there. For example : Just like changing a timing belt on some cars, do the front seal and water pump too.

[@TheWabbit]

I had a 1996 F250 w/7.5L it needed a clutch and the front aluminum cover was leaking, since I had to do both front and rear of the motor I pulled the motor, pulled the heads and checked on the cylinders since I was getting some blowby. Ended up rebuilding the motor. The truck was in good enough condition to last me another 12 years or so why not take care of everything and make the second half of its life a little more enjoyable ( nice RV cam, new intake/Exhaust, heads resurfaced, nice valve job done etc. ) I ended up selling it 6 years later and its living its life on a farm, still going from the last I heard ( it was 4wd w/5speed manual) first year on the farm the guy who bought it went around pulling everyone's animal trailers out of the mud from their back fields as their dually's couldn't handle the excessive rain we had that year. If you're keeping a vehicle, why not do what you need to in order to get better power/mileage and overall performance out of it with the benefit of not having to repair the little things so often.

[@jthonn]

@@TheWabbit You got that right! I have seen people pull engines and not even change gaskets. How stupid is that?

[@mikenicholson2548]

@williamsquires3070 What the hell was that comment. Oh, let me guess, you are into electric vehicles.

[@PhilG999]

I was wondering about that too! With no cats the ECM is supposed to be looking for a difference between the upstream and downstream O2 sensors. What I've seen done before is people after they remove the cats is to put a sparkplug "anti-foul" adapter between the tailpipe and the sensor. There are also "Spoof" devices to fool the ECM into thinking all is good when there no cats. I still think there's a piece of this puzzle missing!

[@StrongDreamsWaitHere]

@@PhilG999 It should run just fine as long as the upstream O2 sensors are working so that the computer can properly control the fuel air mixture in the cylinders. The missing catalytic converter and or failure of the downstream O2 sensors would only throw a check engine light for the emission system. It doesn’t change anything about how the car runs.

[@tomtke7351]

In Florida, not having a catalytic converter can lead to penalties under federal law and state regulations. Removing or tampering with a catalytic converter violates federal EPA rules, potentially resulting in fines up to $10,000.

[@aaronhendrickson]

Talk to the ones that changed the transition. Since the seals were not replaced. It you changed the seals, aka them if you can bill them the labor costs since they failed to change them and caused an oil leak. I still think there are too many wires in a vehicle. I have a solution for the long wire runs. Have the wires combine in to a box that converts the signals over to Ethernet connection so you can run one cable back to the spit point with another box. You can put power over Ethernet. Would help a lot with diage. The ECM can monitor and tell if a wire is broken. A new entry called wire health.

[@ragnarironspear1791]

[@royburgess4720]

[@TriforceOfCourage97]

i dont use mechanics anymore, but even in florida, every mechanic i have ever went to refused to work on a vehicle (especially throwing these kinds of codes) without a converter. I would tell sell the customer 2 converters before I worked on anything else also I have switched plugs also on my car, one for a "purge" valve and one for a "switching" valve. caused all sorts of problems

[@Sam590ss]

I think at this point, if there's anything I do myself, I'm going to ship my truck from Michigan to Florida to be sure it's done right.

[@jefferyberry7010]

Years ago I had hours tied up in trying to locate a random short in my dash and then, I found out that transmission shops are bad about re-attaching the body ground straps. Of course I also discovered that you will end up replacing ball joints and tie rod ends without said strap.

[@bigdog7813]

I ran into a similar situation, although for me it wasn't the ball joints or tie rod ends that completed the ground path, it was the throttle cable (yes, this was many years ago when carburetors were still around). The metal throttle cable would heat up and bind within its plastic housing. Could have led to a very dangerous situation. The problem was a rusted-out/off body ground strap. Replaced the strap and good to go.

[@blahorgaslisk7763]

Watching that door opening when on the lift and I'm so happy it's you and not me having to get through that. I'm not excessively fat, but still I fear I wouldn't be able to squeeze through that. So yes I'm fat even if it's not obesely. For young ones watching this try to stay reasonably fit. It's a hellish trying to work off the fat. Also trying to get rid of fat is working against your body's natural response. Our bodies is the result of thousands of years and generations of natural selection, and one of the things that formed us was the occasional lack of food. A strong body uses more energy and "wastes" it even when not really working. Fat is good energy storage and cheap as it doesn't consume a lot of energy. So if you are starving it's often better for the body to break down muscle mass first, that way you will survive longer and hopefully find more food in time to survive this episode. "So what? That was in ancient time, it's not valid today." Yes it was in ancient time as we see it, but recent enough our bodies are still working that way. Evolution takes time, and drastic changes take a lot of time and many many generations. It also means we have to let nature take it's toll, and currently we don't do that. And I don't really want us to as that would be inhumane the way I see it. Sorry for the way off post, but it's really something that I have watched get worse and worse over time, and it doesn't seem like we have a drastic change coming to solve the problem. So try to stay reasonably fit. It's better for you in the long run.

Nice when other people mess up and you get to fix it. I had a 2003 Chevy with the 4.8l engine. Other than a slight piston slap on cold start it was a really good engine. It had enough power and got good gas mileage for its time. I know it's 20 years old but with a little attention that could be a decent truck. Too bad some owners will put up with all the small problems and only fix things when they have no choice.
