the longer I drive, the longer it tends to pop out. I tend to only get this with highway driving over 15 minutes. i do believe that is completely mechanical. I don't think its solenoid or anything related to electrics. and, with 30wND so cheap, i could swap oil each year, discarding worn oil and debris until that improved. In time, my expectation was that this would get better. this big steel wheel moves back and forth inside that housing, and my guess, for me, was that my replacement was a few thousands bigger than what came out. I was told this might be due to the tolerances. lowers the RPM than what we have, slightly.īut i began having this issue after my swap. its different from the TR set - but not much. in all this, i buy a volvo OD set - essentially the entire mechanical internals. Got hooked up with a former line assembly guy for laycock, who now works for some brit transmission service in england. I had a few threads back in the mid 2000s when gas was 4 a gallon. I also have modified my OD with vovlo internals. if the car is stuck in overdrive, don't back up. Here is what I know, as this is a regular issue for me.īut before I rattle, know this.
