- Resealing the pump of the 4l60e in the 68 gmc. In the process I caused it to have no second or fourth gear so I then had to figure out what went wrong.
This video helped me realize i had to pull mine back out… same issue. Thx for the bad news but she’s working now.
Thanks for letting me know it helped, made my day. Glad you got it going again
Pump alignment during reassembly the first time might have been at least part of the problem with getting the pump back out. Thanks for a great video and nice truck.
Definitely a possibility. Thanks! Glad you like the video
The skid marks were impressive 😂 the posi and the one tire wheel spin. But glad your enjoying your truck
The diff broke so it will get an actual limited slip in the near future, can't do much about the lack of power but it'll have a better chance of doing an actual burnout
Damn that sucks, I hate when if it ain’t one thing it’s another. 5 lug or 6 lug?
Way it goes. Currently 5 lug. squarebody parts up front for disk brakes which made it 5 lug so I got custom axles made for the dana44 to make it 5 lug
Nice. Well hope you get truck out soon for some cruising. Where in Texas? I’m by San Antonio
Thanks, I swapped a square body diff into it for now but the 3:08 gear in it sucks even on the highway. Not enough rpm to keep the TC locked on hills and headwinds. Maybe 1-2mpg better mileage with mostly highway. Rather not say because the internet is what it is
Great video, partner. I'm not sure how you managed to knock the band off the anchor while R&R'ing the pump, but stranger things have happened. By the way, I've rebuilt about a dozen or so of these now, and have had good luck with the TP-50.... just don't do like I did in the beginning and try to use a regular torx T-50.... you'll more than likely be drilling out some bolts. Anyway, cool old iron right there man. Glad ya got that trans fixed.
I'm pretty confident the band came off when we had the trans on the ground and upside down. Hind-sight that was not smart. Thanks for the feedback, so happy to not have to put a drip pan under it!
Did you check codes for failed mass air flow sensor will do that Unless your running a carb with a controller
For a MUCH easier time removing and installing your pump, remove your 2,4 servo.
Why does that make it easier?
@@PracticallyStock it was the install and now I am thinking it may have been because my band wasn't on my stud. But it made it go in SO much easier when I popped that 2-4 servo out. Pump wasn't lighning up streight about to remove mine for the 3rd time. 1st was rebuild, second was replace pump after improper install and hulk smash pump drive. This one will be for that band I might upgrade to pinless accumulators while I am ad it.
Ok so your fuel injected. Yeah better check mass air flow sensor
I refuse to believe a mass airflow sensor can cause the transmission to lose 2nd and 4th. What logic is there behind a mass airflow sensor causing the transmission to lose 2 gears? More to the point, I show in detail what happened and the truck fixed. The problem was not the mass air flow sensor, the band used by 2nd and 4th came unclipped
Sorry, forgot to reply earlier. I did some reading and the MAF can apparently cause some transmission issues by giving a false engine load reading to the computer which causes incorrect line pressure. On some vehicles it will put it into limp mode which may have been what you were talking about, I don't believe this ECM will do that though because it also has a MAP sensor to reference
Like yeah right. 😆
