COMMENTS
JIM: For being brand-new, this transmission looks good. We often see a lot of metal in new
transmissions. It's from new parts wearing in. We also often see high lead, which is marking
compound from the factory. We didn't really find any of that here, and we think your transmission is
looking good as it nears 12,000 miles. You've already changed this oil, so we think you'll find even
lower wear in the next sample. Run that one 20,000 miles before sampling, and don't change the oil at
that point. It should still be good to use. We'll let you know.

The E4OD is acting up at less than 12,000 miles after the rebuild, but the warranty was for one year and it has been almost three. It bangs in and out of overdrive when it is real hot. This oil report looks good, so it must be an electrical problem. The pan was clean and there was just a coating of iron on the magnet.

Note the low additive levels but high flash point, good base oil, weak add pack. This may be Quaker State ATF. Chervron is in there now. It took 14 quarts.

Jim,
This is not a commercial recommendation or endorsement, just a very satisfied customer. I use Lucas anti-shudder additive in my E4OD. I haven't had any issues, I have had my shift points reprogrammed with the shift kit. Shift kit was about $65.00 installed by myself and a friend. Do you have an auxilary transmission cooler? That would probably help. It may not be an electrical problem, but the point in the powerband that it's shifting. Hope this helps.

 

A shift kit, external cooler and the latest upgrades were installed at the rebuild. Shudder is not the problem and it is not "hunting" because of the point in the powerband. I know what both of those feel like. It is not torque converter clutch slippage either. That problem led to the rebuild. This feels more like the fourth gear lets go and the computer then engages third, but it keeps cycling.

Anyway, I am not a fan of Lucas products because of the oil "stabilizer" that appears to be thick oil with a tackifier additive.

Jim

 

Nope, don't use the oil stabilizer. On the whole I think it's a product more suited to large diesels in F800's and up. It is used by our mechanic on the L9000's with Cummins diesels. He seems to like it. Do you have access to anyone with a tuner that can alter your shift points. I am not sure that this will improve the situation but worth a try as it sets hard limits in the computer for shift points. Hope you find your problem and correct it.
