FYI Ray, when removing the valve body, any bolts with nuts on the bottom do not need to be undone until the body is out, they are there to hold the pack together.

99/100 shops would have condemned the transmission. You are one of the very few good mechanics out there willing to take the extra time to fully diagnose issues instead of throwing parts at a vehicle. I would much rather spend the extra money on diagnosing labor rather than waste money on throwing parts at my car hoping it fixes the issue without knowing what the culprit was. No one learns anything that way. Now when the same issue pops up for someone else they know where to look and there’s a solid chance (not 100% obviously) that they may have the same problem with the same make of vehicle. Good work ethic pays off both financially and morally.

[@legionofanon]

Ray you reminded me of a channel I used to watch here, their last video is now about 8 months ago. They are Precision Transmission. Richard gave a ton of great information when it comes to rebuilding transmissions. I think for your valve body you pulled out here, it looks like you only needed to remove the perimeter bolts to remove the valve body. with that it looks like you can reinstall the filter before putting it back in the transmission, especially considering the pass through bolts it has

This one sure did. This is one of the best videos in a long while. I like all of them but now and then something really different comes along. This was one of those times.

As someone who serviced that family of transmission on fleet vehicles, the amount of sparklies is very good. FYI: heavy vibrations are the bane of that valve body. Most 4wd models get new valve bodys around 150,000 miles do to this.

[@abdul-kabiralegbe5660]

Good to know!

[@terminallygray]

I love it when I'm right and Ray, you found the exact cause - which will make the same problem I was yelling about during the first part of this video. The broken trace will take the solenoid out of the picture. (which is same thing, electrically speaking). At the beginning (when Ray was test driving) the transmission wouldn't downshift after it got into high gear, like it was stuck in high gear. I had the same problem on my S-10 that I owned many moons ago. I took it to my transmission man and he knew exactly what happened (common issue). After he replaced the bad solenoid, it worked like new. I got out easy....This guy has to spring for the internal parts of the tranny. It's just "a little" more costly. But Ray had mentioned that problem with GM trucks in his "dealership days".

[@squishy312]

If a newbie like me can rebuild a transmission, you definitely can. That amount of sparklies looks like a normal wear in amount rather than any real damage. The clutches might be slightly smoked, but the solenoids not being connected is a confirmed kill. I'd also recommend looking up the solenoid resistance amount and make sure that they are all within spec. It's just an ohm meter check and really simple. Valve bodies are the way more difficult part than the inside of the transmission. Mine had springen sproings and pistons valves, and a check valve to put in when putting it back in from underneath. It was an extreme pain until I got some super thick assembly grease. Had to take the valve body out a few times cause it was shifting weird... turns out, I had mismatched to giant c-clips on the second brake clutch. After repairing that and resetting the transmission, it ran like a dream.... never needed any valve body work. But I did it anyway, and put a shift kit in it. Looking forward to the follow up vidjao.

[@john_thorpe]

From what I can find online, replacing the V-B would be a lot cheaper than replacing the trans... course it depends on where Ray gets it. Also, from the way it looks, it looks like it comes as one piece with the solenoids attached. So based on that he just needs to unbox and place into the underside of the trans, reattach the filter (or the filter before putting it into the trans cause of the pass-through bolts) replace the cover and fill. Hopefully Ray ordered a new pan as well cause of the bend in the original one. Looks like they used that as a place for a jack when they were replacing the engine... but that's my guess.

[@georgewaring7168]

Totally agree with your diagnosis on that pan John.

[@GReaper]

Agree on the pan, get a new one on there. It would be fine as is, but since its structure has already started being compromised, a new one is a good idea. Also, the filter/strainer should be replaced since he's down there, as a matter of course. Although he may run the old fluid first to confirm fix, then change it when changing the fluid.

[@StrongDreamsWaitHere]

Even if Ray bought a whole new reconditioned transmission and just swapped the valve body, it would be cheaper on labor alone.

You can explain the options and change or give no warranty for the option the customer selects. For example tell the customer about the other wear and give the option to the customer to change the valve body or the entire trans. If you change one part inside the trans only warranty the part and write it on the bill. " Needs entire transmission replaced cust did not want replaced at this time. If transmission fails within 90 days credit paid for labor will be given to cost of labor and parts of total transmission replacement"

Every time I get a transmission that I have not worked on before I buy the manual. Gives me all the information needed to do the rebuild.

Nice piece of work. Now remember it appeared there were TWO solenoids with no current. You found one with both connections severed. By my math that leaves one unaccounted for. I suggest checking each solenoid with your ohmmeter. I don't know the correct resistance values but it wouldn't be very much, perhaps a few ohms. Replacing some or all of those may not be a bad idea if you can get them.
