Call Jamie Passon- Passon Performance - you know the 4 and 5 speed guy. He has his own proprietary transmission lubricant for mopar 4 speeds. There is a significant difference between his lubricant and the off the shelf products that many will recommend. btw I torture tested the Passon product and the OFTPs and his by far performed the best.


For Jamie Passon's new 5 speed tranny, he recommends Lucas Synthetic 75W90. I believe all his testing was done using this lube.

So does he still recommend his lube for our older 833s and 833ODs? The syn 75w90 is also recommended for Sure-Grips, which flies in the face of most recommendations for the 833.

This is getting a little bit complicated.

Could we just mix gear oil and ATF half and half as a compromise for our 833s?

Master, again and still
