The 4L80 uses solenoids to shift. I'd verify they are working and also check the harness from the solenoids to the PCM. When I bought my 94 it wouldn't shift at all. I build a little stand alone box with toggle switches and plugs for the transmission and a cig lighter plug to feed it 12V. That...

My 94 Chevy 3500 has a new "issue". On the weekend we were pulling downed trees and I was doing so in 4WD Low. While pulling a tree (likely about 2000 lb) I heard a bit of a bang and the truck wouldn't move. I shut off the truck and restarted, placed the trans in Neutral and tried to re-engage...
I'm having the same issue with my 94 3500 5.7 truck. New starter/solenoid. Took it out today. Started fine, went to the dump to drop off a bunch of crap and the truck wouldn't start on the scales going out. Not even a click. Checked my connections and they looked ok. Had to get a push off the...
I had a similar issue. My guages and lights would flicker and the truck would hesitate- only when driving. Found both ground straps rotted off. Replaced and it's all good
My 94 K3500 5.7 does the exact same thing when cold. Feels like an old carbed vehicle that hasn't had time to warm up properly. I've yet to find the cause.
I'm about to replace the fenders and inner fenders on my 94 Chevy 3500. I removed them as one unit. Would it be easier to install them both as a unit already bolted together or install the inner first and then the fender?
Thanks

It's been fairly cold here in PEI lately (-14c at night). We had about 15" of snow last week. I plowed out our lane and lot next to our property.. That night we had some heavy winds from the west and a -22C windchill. The next day the truck wouldn't crank- just a light "click". Since the battery...
I live on an Island in the Atlantic in Eastern Canada. The roads are salted heavily in winter and the air is salty. We had wind chimes on the back of our house. One day I noticed they didn't chime anymore. I found the chimes on the ground- the metal chain had rotted thru from the salt air! I...
