I was changing a auto trans filter on my newly purchased preowned 99 K1500 GMC (older style) truck. After removing the filter I thought I was supposed to remove the rubber gasket that goes around the filter neck from the truck (it didn't come off with the filter). I notcied that this filter is different than the filter on my other '92 K1500 Blazer - that filter has an orange o-ring, that you change along with the filter. Anyway on the 99 trick, I removed this gasket and now it looks like I shouldn't have - it looks as if this gasket supposed to stay in the trans. Most of the gasket is now damaged and cannot be reused. I don't think I can put the filter back in the truck with some of the gasket missing (the top part is now missing). Has anyone ever done this too or can anyone offer have any advice. I was thinking of trying to get the gasket at a GM dealer and then replacing it.

Do you have the new filter yet? It should come with the fitting you describe. I have a 97 and this fitting is metal with a rubber seal that the filter neck slides into. Its a PITA to get the old one out on my truck. I usually use a flat screw driver to twist the old one out. I use a fat wood dowel to tap the new one in place.

 

Hope that helps.

Try this http://www.sears.com/sr/javasr/product.do?...Specialty+Tools

 

Works well.

 

The best way would be to use a blind hole puller but expensive http://www.thetoolwarehouse.net/shop/OTC-4581.html http://www.otctools.com/frames-newcatalog.php3

 

Other's use a screwdriver to bend the seal enough to pull it out with a pair of needle nose pliers. Some use a file and cut through the side of the seal. YOU SHOULD MAKE SURE YOU DON'T SCORE the transmission bore which could cause leaks. Some just leave it in there and put the new filter in because it's to hard to get out but since your's is already damaged you should remove it completely and replace.

 

The transmission filter comes with a new seal.

That tool looks like something that could be easily made. Appears to be just a threaded fitting that screws into the seal and onto a slide hammer.

Has anyone tried to make anything like this? I dont have a slide hammer, but since I am thinking of changing my trans filter today maybe I will see if I can find something that fits.

A '92 truck should not have a 4L60E transmission, as it was not an OBDII vehicle. It should have a 4L60, however. Same transmission with the exception of the electronic controls.

Like you this looks relatively simple. I would simply take a piece of pipe slightly larger than the ID of the seal, weld a nut on it that will fit on a small slide hammer, then thread the pipe the opposite thread direction. It wouldn't be that hard, I wouldn't think.

I just did this on my '99 with the 4L80E. That seal was a pain in the ass, but with some persuasion, and a few choice word's, I was able to get it out.

      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.
