<div>Back when Mike Belfer was prepping my race car, I understood him to say that the TR transmission liked one oil weight and the overdrive liked another. Therefore the oil he used was a compromise towards satisfying both. </div>

<div>This was back in the 1980s, and I cannot recall the brand (maybe KENDAL, but I'm not sure).</div>

<div dir="ltr">In the gearbox that Tim is referring to, I used a brand new re-lined <br clear="none">cone clutch in an OD unit that came from Bill Dentinger with Old Blue. <br clear="none">No clue what the history of the unit was, but the cone clutch stuck to <br clear="none">the brake ring in earnest for a several sessions. Operating pressure is <br clear="none">in the low 400's. I did replace the oil with Redline MT-90 during my <br clear="none">efforts to get the OD to release, and I am assuming the MT-90 helped. As <br clear="none">Tim said, there were several laps around the paddock that first weekend <br clear="none">with the car with the gearbox cover off and a mallet in hand, but it <br clear="none">wasn't until the second weekend out with the car that the cone clutch <br clear="none">released by itself.<br clear="none"><br clear="none">It is worth noting I didn't like the shifting feel with the Redline and <br clear="none">went back to Brad Penn gear oil. That OD unit has been in the car for 20 <br clear="none">race weekends now, and other than the need to bed in the cone clutch, it <br clear="none">has performed flawlessly.
