Suprisingly, I've been receiving a fairly steady stream of status inquires since I killed my transmission in July/August (after the FMIC install).<p><IMG SRC="http://i325.photobucket.com/albums/k395/mrosineo/tombstone.jpg" BORDER="0"><p>So, for those who were concerned, (as well as for future researchers of S80 transmission threads) I figured that I'd post an update.<p>But, since this <B><I>IS</I></B> an S80T6 I am talking about - I'd better take a few precautions:<p><IMG SRC="http://i325.photobucket.com/albums/k395/mrosineo/flamesuit.jpg" BORDER="0"><p><br>Ok, that's better. <br>Now, on to the update...<p><IMG SRC="http://i325.photobucket.com/albums/k395/mrosineo/IMAG0057.jpg" BORDER="0"><p>I finally got around to having the transmission pulled. It'll be dropped off on Tuedsay for a complete overhaul consisting of a high performance street/strip rebuild (clutches/bands,valve body, shift kit, etc...), upgrading the input shaft to a stronger unit, upgrading the chain to a 7/8 single chain, and (drum roll please ...)<p><br><IMG SRC="http://i325.photobucket.com/albums/k395/mrosineo/IMAG0057.jpg" BORDER="0"><p><br>Changing the stock convertor's stall speed to approx 3K. <p>The transmission rebuild is being done by this guy:<br><A HREF="http://www.tripleedgeperformance.com/" TARGET="_blank">http://www.tripleedgeperformance.com/</A><br>Expected turn around is about 2 weeks due to the custom convertor work<br>I've asked him to provide a post mortem analysis so others can benefit from my transmission's death. <p><br>That is all.<p><br>EDIT: added link to website<BR><BR>

awesome!<p>so one thing i found out was that the differential wasn't compatible with the HD differential from the 4t65hd. there was something about the speed sensor location... what i didn't learn was if the volvo version was comparable to the HD nonetheless, or did they go with the weaker modified standard one.<p>

Re: (SkyWriter)

I dropped the transmission off with Dave from TripleEdge Performanance.<br>We chatted for about 30 minutes. He said the he does rebuilds for the 4T65E units about 150 times a year. Also said that GM's version of the diff can't b be easily swapped with the Volvo version - and that it really wouldn't matter because he has never seen a reliable limited slip differential for these transmissions<p>I'll ask him your question when I speak with him again.

Re: (osineo)

Interesting, one of the first ive heard thats done a rebuild upgrade on the 4T65. Being that we replace these trans bout once or twice a week curious to see the reliability of this sort of rebuild, cool project <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">

I havent seen any that have been a problem yet and they seem to hold up very well in the Volvos"

Re: (osineo)

excellent! building up the rest of the transmission without knowing if there was a weak differential bothered me to no end <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0"> i think i'll budget sometime this winter to get the transmission out of my parts car for a rebuild. when do you expect you'll have your installed?<br>

So were there no bearings, gears, shafts, splines, etc. gone bad? Were the clutches replaced? And what if anything was done to the valve/body assembly?

If it's done and the car works before Jan 3rd I'd love to come down and check it out if you don't mind...

Re: (osineo)

The rebuilt transmission is back in my garage.<br>The official cause of death was the clutch/bands, but he said that 4th gear would 've died in another 1000 miles or so. There also was evidence of extreme heat inside the transfer case <br>( I wonder why <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0"> )<p>In addition to the HD Input Shaft, converting to a 7/8th single chain, and getting a street/strip rebuild the case was cleaned and painted. (just like on his website)<p><IMG SRC="http://i325.photobucket.com/albums/k395/mrosineo/IMAG0089.jpg" BORDER="0"><p><IMG SRC="http://i325.photobucket.com/albums/k395/mrosineo/IMAG0090.jpg" BORDER="0"><p>The torque convertor was sent to Precision Industries (<A HREF="http://www.converter.com" TARGET="_blank">http://www.converter.com</A>) to have the stall speed changed. Apparently, each convertor they touch has to leave the shop dipped in fuchsia. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/eek.gif" BORDER="0"> Thank goodness it's hidden by the belhousing<p><IMG SRC="http://i325.photobucket.com/albums/k395/mrosineo/IMAG0093.jpg" BORDER="0"><p>I was suprised to receive a gallon of this:<p><IMG SRC="http://i325.photobucket.com/albums/k395/mrosineo/IMAG0095.jpg" BORDER="0"><p>He said something about transmission fluid having the viscosity of water, and that this transmission/drive train oil from Catapiller will help to break in the transmission and extend the life of the unit.<br>Instructions said to pour this in the trans before starting the car along with 2 quarts of Dextron3, start the motor and top off the transmission with more Dextron 3.<br>I'm not sure if he wants me to use this each time I flush the trans or just this once. <p>I also picked up a new transmission cooler.<p><IMG SRC="http://i325.photobucket.com/albums/k395/mrosineo/IMAG0092.jpg" BORDER="0"><p>Break in consists of 50 -100 miles of city driving which will give the kevlar material inside the convertor time to bed correctly, while also allowing the pcm time to adjust to the new transmission<p> <IMG NAME="icon" SRC="http://www.vwvortex.com/zeroforum_graphics/biggrinsanta.gif" BORDER="0">

Re: (osineo)

Thread epilogue:<br>Well, the transmission is in the car, my 100 mile break in period is over and I thought that I’d add a final update and some closure to this thread.<p>Let me preface this by saying that right now, the car is limiting boost to 10-12 lbs. Why? I don’t know yet. Could it be because the “Service Transmission” message is still on? (My code reader won’t reset TCM codes so I’ll need to visit the dealer to have it reset). Maybe it’s because I also have a CEL. I didn’t bother to pull the CEL code(s) because I figured I’ll deal with it later this week. <p>Also note the tires were changed to my winter set which are 17” Potenza’s. Weather wise, the high temp was around 25 degrees today – which meant cold street surfaces (less traction). <br>Finally, consider that fact that I’ve been driving the 05 Odyssey for 5 months – so my butt dyno needs to be re-calibrated. <p>And with those disclosures, here are my initial impressions:<br>Around town driving has definitely changed. The transmission feels “tighter” and shifts firmly. When leaving from a light, the stall feels similar to driving with the transmission in winter mode. The TCM still seems to be learning the transmission because the up-shifts aren’t as hard as they initially were, but the down shifts are pretty violent when in GT mode. Brake torquing the stall results in 2800 rpm launches which totally over-power the current tires. <p>At highway speeds, this car really shines now. Passing gear is wicked - compared to stock. With the fmic, the car doesn’t seem to run out of breath up top during 40-120mph pulls like it did in the past. <p>Over all, I am pleased. After I clear all codes and change the plugs I’ll see about posting a video or two. <br>

Pretty cool, glad you put this up. Are you losing traction anymore then you used to in similar weather conditions?
