    Cooked 700R4 update

    I made a post last month about my 700R4 transmission on my 84 K10 not wanting to shift into 3rd gear. Then on the drive home it started slipping and would barely even drive. Well I've been procrastinating, trying to figure out what to do because they said it was out of warranty, but they "stand...

    700R4 hits 45mph then kicks into 1st gear

    Lol. The tranny probably burned up because it couldn't handle all the ponies coming from the 305 powerhouse. What is a NV4500? How extensive is the swap? And what are the benefits? What are the cons? Sent from my SM-G950U using Tapatalk

    700R4 hits 45mph then kicks into 1st gear

    I have no idea what an ATRA shop is. But I'll check when I go there. But, the warranty is up. But they told me they still stand behind their work, warranty or no. We'll see Sent from my SM-G950U using Tapatalk

    700R4 hits 45mph then kicks into 1st gear

    I'm hoping they'll warranty it. If not I'm going to weigh out my options, and pick another tranny shop. Sent from my SM-G950U using Tapatalk

    700R4 hits 45mph then kicks into 1st gear

    I will let you know what they say. I'm working on the cheapest way to tow the truck to the transmission shop a hour away. I'm hoping they'll warranty it. Tranny should be able to get more than 2,000-3,000 miles before it craps out. Sent from my SM-G950U using Tapatalk

    700R4 hits 45mph then kicks into 1st gear

    At least I'll know for next time. Is a 700r4 just a weak tranny? I had it rebuilt last year, but I doubt they built it up of anything. Sent from my SM-G950U using Tapatalk

    700R4 hits 45mph then kicks into 1st gear

    Do I not put the truck in OD while towing? I just assumed it wouldn't shift into OD if it wasn't okay to do so Sent from my SM-G950U using Tapatalk

    700R4 hits 45mph then kicks into 1st gear

    It's possible, well the tranny is cooked. It started slipping like crazy when I got close to home. I can smell it now too. Burnt tranny fluid smell Sent from my SM-G950U using Tapatalk

    700R4 hits 45mph then kicks into 1st gear

    The tv cable seems to be adjusted properly. It hasn't moved from where the transmission shop placed it and it moves freely. Another transmission shop I called says it sounds like a sticking valve body to them. Guess it's going back to the transmission shop that did the rebuild so they can see if...

    700R4 hits 45mph then kicks into 1st gear

    Tv cable seems to be adjusted properly. I noticed that it seems to shift back into first when it should be shifting into third. Another transmission shop I called says it sounds like a throttle body is sticking. And he said that means something is probably coming apart internally Sent from my...

    700R4 hits 45mph then kicks into 1st gear

    I just towed a fairly lightweight trailer with my 84 K10 305 v8 yesterday. It towed pretty good, although the severely limited power output of the 305 was annoying. But, today when I drove it the to return the Uhaul trailer the truck decided to shift down into 1st gear when I hit 45 mph. Luckily...

    1980 C30 running rough solved!

    So you think a look inside the gas tank would be a good thing to do? Sent from my SM-G950U using Tapatalk

    Air bubbling into the fuel filter

    I want to stick with a clear filter so I can see how dirty my fuel or tank are. On my truck I have a glass one, but my father in law didn't want to spend that much money on one. I guess we'll go ahead and replace all the rubber lines. I'm sure they're probably original. Sent from my SM-G950U...

    1980 C30 running rough solved!

    I posted a while back about my father I laws 1980 C30 truck and how it died on him and we couldn't get it to run. It turns out that the carb was full of rust powder. I'm not really sure how because he just replaced the in line fuel filter that is just before the fuel pump and I just rebuilt the...

    Air bubbling into the fuel filter

    On my 1980 C30 truck I notice that there's mostly air being pumped from the fuel pump into the plastic fuel filter just before the carb. When I say air I mean a lot of air. I can barely see any fuel making it into the filter. Even when I turn the fuel filter on its end so the fuel he to enter...

    80 C30 fuel filler neck

    Yep, I guess the bed is supposed to be raised. I guess we'll just bend the support rod up and replace hoses. Thanks for the help Sent from my SM-G950U using Tapatalk

    80 C30 fuel filler neck

    We're trying to find a solution for my father-in-law's 1980 C30 with a dump bed. The problem he presented me with is the fuel filler neck is lower than the tank and when he pumps gas he has trouble. "No problem", says I, "there's a steel rod that holds the end and we'll just bend it up higher...

    Is this a small block or big block engine?

    Okay, I've got some new info on the situation. He told me that when he stopped the truck to look at it, the ground for the choke had worked itself off the post. So he reconnected it and finished driving and he said it still ran poorly. I just went and started it and the truck was very hard to...

    Is this a small block or big block engine?

    The verdict is in. I have a small block and a 2 line fuel pump. Thanks for the help everybody. Sent from my SM-G950U using Tapatalk

    Is this a small block or big block engine?

    The truck has a dump bed, so it'll be easy to see the tank. Sent from my SM-G950U using Tapatalk

    Is this a small block or big block engine?

    More than likely I just missed a hose then. Tomorrow I'll actually crawl under the truck to check. I may replace the pump regardless just to have one less thing to worry about. They're only $20 and I'm sure it's the same pump for at least 20 years.

    Is this a small block or big block engine?

    I'm definitely going to check again then, before I order a pump. Can a failing fuel pump cause bad hesitation, backfiring, and missing? My father in law had a really hard time getting the truck home the other day. We just changed out the carb for an Edelbrock 600 CFM that I rebuilt and I'm...

    Is this a small block or big block engine?

    I will double check that the fuel pump is only 2 line, but just from feeling I'm pretty sure it was.

    Is this a small block or big block engine?

    Thanks. My truck still had exhaust tubes and I had my muffler guy snip them off with a torch and he brazed the holes closed.

    Is this a small block or big block engine?

    Awesome, thanks for the info. Now I'll always know how to identify a small vs big block. Why is a 2 line fuel pump for this engine so hard to find? Everything I see has 3 lines.
