I have a 2001 silverado...Just installed a 246 with 272 from an 04 silverado. My old transfer case is the same model. After installing it i realized the harness on the transfer case motor does not match the one on the truck..im assuming they changed the design? So i decide to swap the motors(old one worked). Thin is my old one has an oval shaped gear and the new one is round. Checked the wires to see if i could splice the pigtail from the old. Original had four wires, the new one has 6 or 7. Four of the wires match up but don't know what the rest are for. I also have an extra harness with nothing to plug into because the old tran case motor had a female connection on the face of it to plug it in to. Not sure what to do..any help would be greatly appreciated....UPDATE! rewired some thing all i have left are three wires wih no where to go..they are coming off of the truck (yel/blk)(red/wht)and (dk blu/wht). Started the ruck like that but have the service 4wd light..does it need to be reflashed?

      TCM Tuning 6L80E

      I did the new thermostat after doing a 'flip' for a year. Runs as cool one way as the other in the summer but in the winter there is a bit of a floor. Yellow with the new 70 C thermostat. My data over the life of the unit to date. Still need more cooler. Anyway that floor helped both winter fuel economy and shift quality in the winter. I found it a good balance.

      Evan Williams Bottled in Bond   So pouring the last of a bottle of Evan Williams Black label last night I set off the the state store for a refill only to be denied the by an empty shelf. Rats.    What the did have was a bottle of Evan Williams Bottled in Bond. 100 proof. Hum, a few bucks more but a known distiller. Lets have a swing at it. ( I have before )    Cracked it open and pour a serving over ice. Hum.... more heat, yes. More alcohol naturally. But the barreling not the proof brings the taste and this one came up short.    Oh is was familiar but the heat ran the barrel over like a Peterbilt runs over a squirrel. Could use a heavier toasting of the oak me thinks or perhaps a longer barreling. Who knows. But what I can say is ice or a water back isn't the answer. What kills one kills them both. Sad. It is a pleasant drink....if you have little to compare it to.

      Bridgestone vs Goodyear tires?

      By Grumpy Bear · Posted

      I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Atlas, you kill me As aggravating as a project like this can be you have been unable to hide your fascination with learning and using that angst against this beast like a Ninjitsu Master. It amuses you, admit it now.      BTW, love your writing style. 😉

      I gotta say, I'm enjoying your narration. The troubles you've been having are amusing as you describe them. It's good to see that you're finally getting some satisfaction out the old beast though.
