    1994 c2500 no second gear

    Im not 100% sure of water. So there is no possibility that the 4l80e overfilled by a quart or so will cause it to not engage into second? Like i said it will engage when full throttled sometimes. Also would it be possible to rebuild a 4l80e with no transmission experience at home? And how much...

    1994 c2500 no second gear

    Hey i just got a 1994 c2500 with a 4.3 and 4l80e trans with 77k miles for free. Guy said it had no fluid on the dipstick. I put about 2 quarts of valvoline dex/merc in it(i know it should optimally be dexron VI but its what i had laying around) So driving it, truck does not shift into 2nd 70% of...

    94 k1500 brake shoe and drum size

    I thought that if you feel the shake in the steering wheel then it was the front rotors, if felt in the pedal then it is in the rear. Could i be wrong?

    94 k1500 brake shoe and drum size

    I tried the parking brake thing. It doesnt go to the floor but it definitely does not stop the truck, also the pulsing thing with the brakes is more of a high speed thing. As when im trying to brake going over 50 then its really noticeable, any less and its not very noticeable. Not sure how else...

    94 k1500 brake shoe and drum size

    Im fairly certain its the rear drums because i didnt have this problem until i slid into a curb and bent my axle shaft which made the drum rub the brake nonstop going down the road so i assume it got hot and warped or created hotspots on the drum. Im only replacing one drum. Im just seeing if...

    Brake lights won’t work?

    personally i have the same truck (94k1500) and i had the same problem with my brake lights not coming on. first you should see if your third brake light comes on when pedal depressed, if it does its most likely a wiring issue. If it does not, what i did was get my hand under there and find the...

    94 k1500 brake shoe and drum size

    My brake pedal is pulsing pretty bad. I assume its my brake drum in the rear that warped. When i looked up on autozone it appeared there was 2 different sizes for these trucks. Whats the difference, i assume one is for a heavy half? Im not sure.

    10 Bolt Diff

    I actually just swapped it yesterday. I did not know all you had to do was push the axle in to take the c clip out, coulda saved me an hour of work but both axle shafts are the same on a k1500p/u and a gmc k1500 suburban with govlock

    How hard was it to troubleshoot that? Did you have to pin out and check resistance on the wires?

    Knock or backfire?

    Its a 94 305 tbi with 230k miles. Doesnt burn oil or anything and it wasnt doing this before somebody pulled apart my Y pipe and the donut disappeared.

    Knock or backfire?

    I have a 305tbi and when it revs high it sounds exactly like a rod knock. My donuts for the Y pipe are basically non existent. Is it a backfire caused by valve float or is it something else. It makes the noise while in gear but also when its in park and i rev it. It follows after with no power...

    Ran transmission 2 1/2 quarts low

    I have obd1. I usually just stick a piece of wire in it and it blinks me a code. BUT my check engine light does come on whenever i go above 50 but it turns off whenever i make it to my stop. Should i just bring it to a transmission shop and have them diagnose it? I heard my local one is pretty good.

    Ran transmission 2 1/2 quarts low

    It is the 1-2 shift. Itll shift hard unless i let up on the pedal to let it shift then its smooth. I dont know what the difference is between a hard and crisp shift? The 1-2 is definitely noticeable if i dont let up. Also sometimes when im going above 50 or so it will shudder? Or something? I...
