Mikelly Posted September 18, 2003 Share Posted September 18, 2003 SO Monday while I was at the specialist, We had dropped the truck off for new tires in the rear, and on a whim I told them to do a BGs Trans flush. The fluid was 125,000 miles old and I figured it wasn't gonna help since the trans has beed acting up a bit, making a high pitched noise once in a while for just a second... Shifting at funny times, and slipping once in a while. I picked the truck up and noticed the trans shifting much firmer, and more precise, no noise, no slipping. I've driven it for 3 days in rush hour traffic and with a heavy foot and it seems to doing GREAT! Can it be that a simple trans flush sucked out whatever the offending matter was?

Tim240z Posted September 18, 2003 Share Posted September 18, 2003 Mike, Tranny fluid does a lot, so if it's bad, a lot doesn't work. When the fluid is old and contaminated, it foams up easily, thereby losing pressure and it's ability to pull heat away from the tranny. Yeah, many times a batch of new fluid will make a world of difference! Tim Quote Link to comment Share on other sites More sharing options...
Mikelly Posted September 18, 2003 Author Share Posted September 18, 2003 Tim, I realize it matters, but to illustrate the significant difference in performance, I was ready to replace the trans earlier this month... This is NOT the same tranny... I'll be doing this every 50K miles from here on out! Mike Quote Link to comment Share on other sites More sharing options...
Guest greimann Posted September 18, 2003 Share Posted September 18, 2003 Have you ever looked at the valve body of an automatic? It is an extraordinary complex set of passages, orifices, check valves and black magic. One little ball of crud somewhere in that mouse maze could stop the whole works!

JMortensen Posted September 19, 2003 Share Posted September 19, 2003 BG makes great stuff. Their power steering flush is worth it too for anyone who has a vehicle with power steering. It was the first thing we did on all 944's when they came into the Porsche shop I worked for. They also have some AWESOME axle/cv grease.
