Re: [MBZ] Lucas Transmission Fix
SUggest you buy another used one from LKQ. They have a good warranty.

I've got three other vehicles, so it's not a daily driver. Again, good luck to both of us.

[MBZ] Lucas Transmission Fix
Mitch, My 1980 300SD with the used tranny installed a year ago slips between 2/3 and 3/4 under medium load. I just had it serviced and had a bottle of Lucas added. Lucas claims to fix slipping, hard shifts, etc. etc. There was no immediate improvement as some claim on Youtube. I'll report back as well once I've driven it awhile. If it doesn't show improvement, I'll take it back to my Indie for a drain and refill with regular ATF. My Indie thought I was crazy (maybe I am), but he didn't see how a product could fix both hard shifting and slipping as they are at somewhat opposite ends of the problem scale. But I'm still open about it so I'll wait and see. Good luck to you too. Best Wishes, Roger Roger Hale Dinnerware Classics, Inc.
