I went to a Chev dealer only to find You must buy the entire wiring harness at a cost of $2,485.00. After I got back up off the floor I was told that they used to make just the plug with the lead wires; but do not anymore, & no more in stock! Then found out very few of the 80E transmissions were made for a 1994. Went to a repair shop, & asked someone I know to find one at a junk yard. The person spent days trying to find one on the internet junkyard websites including going to a large junkyard to see if he could find a plug on a close model year. After 4 1/2 hours crawling through the mud He gave up. Said he must have checked 30 - 40 vehicles! None had the 80E transmission! Any help appreciated! Scotty [Reply]  [Send Email]

Most of them are an "60E" As a matter of fact the Owner of the shop said He had only replaced 2 of the "80E"'s in the last 10 years or so in a 94 chev that he could remember, & was vey surprised that mine was one! He went to a junkyard, & looked at around 30 - 40 Chevy 2500's, & NONE matched the plug on mine. By the way; The plug in question is for the speed sensor I believe. I am driving the truck now; But cant use the overdrive. When in overdrive it shifts straight into 4th gear from 1st. The computer shows that the truck was running 112mph with the cruise set at 55mph, & it was moving at around 55. I would have to crawl under the vehicle to look at the plus. I personally did not see it. Scotty   [Reply]  [Send Email]

Now, the '92's and older had the 4L80, not E. I think. So you need to find a '93 or newer, and again I am almost sure all K2500's use that tranny, of course unless it was a manual.   [Reply]  [No Email]

Once in a while you can find a similar shaped and keyed plug elsewhere on that vehicle or others. Or even in one instance I had where the new part was keyed different from from the original, a little bit rework with a sharp blade made it fit just fine. Otherwise if the part can be removed, someone deft with a soldering iron can solder wires into the part the plug attaches to and you can use something more common to mate to the main harness. Had to replace a harness in old Ford, and the reason those harnesses are so expensive is that they are made up by hand. one at a time. I had to rework mine because they put two wires into the wrong plug.   [Reply]  [No Email]
