    Transmission Issue ??

    Also if it controls both carb and lock up that could explain why I am also having a stalling issue at similar times with warm weather?? Truck will stall while driving as if there is a fuel problem. Pull over and will start back up in minutes.

    Transmission Issue ??

    Thanks for you efforts! Are you thinking this switch/sensor in the pic is the one for both carb and lock up?

    Transmission Issue ??

    Couldn't find another switch except the one pictured earlier. Is it possible it is missing the switch?

    Engine Stall and Transmission issue-85c10

    The time it takes for it to happen really depends on outside temps. On a warm day it can occur in 10 mins, the other day it took 30-40 mins before it starting acting up. Engine runs about 210. Cooler lines look fine as well as the fluid. During winter months no issue. What do you suggest I do?

    Transmission Issue ??

    Ben--Is this the switch? It is located on my fire wall. Forgive me in advance for all the questions. What does the delay valve do? Using the Ohm meter will tell me if switch is good or not? Is it ok to drive with vacuum switch unplugged? Does that prevent lock up from engaging? How is that...

    Engine Stall and Transmission issue-85c10

    The charcoal canister line is hooked up. The 2nd line to fuel pump is not hooked up which I believe is a return line back to tank.

    Engine Stall and Transmission issue-85c10

    Just noticed my fuel pump has 2 lines but truck has 3 coming from tank. 3rd line is not hooked up to fuel pump which I assume is a return line. Wonder if I replace with 3 line fuel pump that could fix issue??? Sent from my iPhone using Tapatalk

    Engine Stall and Transmission issue-85c10

    1985 C10 350 engine, 700R4 Transmission, Holley Carb I am having two issues and unsure if they are related or completely separate. Both appear to be triggered by heat. I purchased the truck last year and as temps increased over the summer I began having stalling issues as well the truck would...

    Door #1 is opening and closing — would it do that with a vacuum leak? Sent from my iPhone using Tapatalk

    A/C Blend/Mode door issue

    Heater Core Replacement- Need part

    Thanks yevgenievich...I was able to pull out the nail pin. Another question--the insulation(??) on the inside got damaged from the leaking heater core. Can I get a replacement piece for that section or should I use adhesive to glue it on?

    Heater Core Replacement- Need part

    In the process of replacing heater core on my 85c10 and noticed a broken part. I believe it's a diverter Valve link connector. It goes on the bottom of the heater core assembly box and helps control door flap. I was able to find the plastic piece replacement part but it doesn't come with the...

    Transmission Issue ??

    Thought the stalling issue may be related or do you think that is a separate issue?

    Transmission Issue ??

    Would that mean the vacuum switch is bad or engine has a vacuum issue?

    Transmission Issue ??

    Took it for a drive today, still with lock up unhooked, and it stalled while driving after about 30 mins. Started right back up and drove with no issue. Truck did not lunge this time while driving. Unsure if the stalling is related or a separate issue. Going to hook lock up wire again to see if...

    Transmission Issue ??

    I unplugged the lock up connector wire and so far appears that the issue has stopped. Suggestions on what I should/need to do or what exactly the issue is that needs to be fixed?

    Transmission Issue ??

    Fluid looks fine. If I take foot off peddle or accelerate the issue stops. Only occurs when cruising or at a constant speed (ie. driving at 45mph). Also only after driving for awhile....doesn’t happen on short drives. Leads me to believe temperature is causing the issue Sent from my iPhone...

    Transmission Issue ??

    '85 C10 w/ 350 and 700R4 transmission. Truck is new to me and after driving for about 30 mins and it has warmed up the truck will begin to lunge forward on its own at cruising speed (40mph +) without any acceleration by me. Only does it after it has warmed up and once in 4th gear I believe...

    Vapor Lock issue?

    Thanks for the responses. I am actually thinking the engine reving/lunging on its own and the stalling are non related issues. I relocated and replaced the fuel filter and haven't had the stalling issue since but once engine heats up and in 4th gear it lunges forward. Someone suggested it could...

    Vapor Lock issue?

    Recently purchased 85 C10 and been having issues after driving for about 10-15 miles. Once at cruising speed the engine seems to slightly rev itself as well at one point stalled on me after sitting in traffic for some time. Also live in Phoenix so it has been warm. Vapor Lock issue? Any...

    Engine Stall--'85 C10

    Took my truck for a drive today and stopped to get a drink. I was waiting in line for about 15 mins with engine running (AC off and temp stayed around 200 degrees) and once I drove away I kicked on AC and about 2 blocks later the engine stalled. Pulled over and waited a few minutes and truck...
