That's interesting because I have a 2002 Fleetwood, on a 2001 Workhorse W22 chassis and it had Dexron in it. Does this mean that the Allison T1000 transmission in our chassis was from pre 1999?

Not that this is a bad thing, but maybe they didn't switch the smaller transmissions until later than 1999?

Just asking.

powerboatr,

To my knowledge, we never tested anything but the factory filters so I have no data on other "after market" filters. They're spec'd based on media size, efficiency (beta rating), and capacity.

thank you

you answered it but in a way some might not agree.
if a manufacturer of an item has "XYZ"spec for its filtration and then either builds its own filter system or asks...say a filter company to build a filter that would achieve the spec "XYZ" and it does in fact meet the spec, then it should be OK for use. some say fram, wix, motorcraft, k&N, baldwin, etc are or could be garbage...but if they meet the spec set out by the manufacturer, then in essence they should be ok for use.

i found it interesting that cummins recs, fleetguard filters....and Valvoline premium blue oil, Valvoline like castrol for the transynd has a licensing deal for its use like you mentioned allison gets $$ for every gallon of transynd purchased.
but at most OTR shops, they use baldwin filters on the engines????


i appreciate your great help here.

remember it took most car buyers over three years to figure out that the new saturn car company was actually a GM product and even then there were many in denial

Tom, My sample came back with a elevated lead and boron. not bad, but high for trans. boron was 112 and led was 16. Also my Cst @ 100c was 6.9. Close enough to 7.0. It had 25,000 on it and was second change after first 500o miles. Total now is 36,500 miles. It's an '06 4000 What do you think?

powerboatr,

The problem is that Allison does not have an filter spec. The filter spec is on the original drawings for the factory filters, which are proprietary to Allison. The filter specs are not published. Therefore, no one in the aftermarket can reproduce the filter performance because there's no spec to test against.

Perry,

Don't know who did your analysis but lead at 16 ppm is extremely low. No worries there. Boron is from the additives package and is part of the dispersants. 100C viscosity of 6.9 is good; I wouldn't be concerned unless it reaches 6.0 cSt and that would be very unusual. TranSynd can't lose viscosity so 6.0 would indicate somebody topped it off with DEXRON-III since DEXRON-III's are famous for losing viscosity in a relatively short period of time.

I think you're in good shape. I'd say keep on trucking and keep doing oil analysis. Who did the analysis?

Transmission Service

Appreciate your willingness to answer questions on this topic. I have a 2004 Journey with the Allison 3000. Bought unit this winter with 23,000 miles on it and in reviewing the service records noted transmission had not been serviced. Took to a Winnebago dealer in Henderson and requested transmission service. Unit was serviced, oil and filter change. When paying the bill I noted Dextron 111 was used to refill rather than transdyne oil. I questioned the point and was told my unit had Dextron 111 coming in so used same on service unless customer requested otherwise and it would not be a problem. Transmission Service required again in 25,000 miles and if I wanted to change to transdyne oils do it then. My review of Allison web site left me believing Dextron 111 is not an issue in the 3000 transmission unless I'm reading it incorrectly.
Appreciate your opinion
Thanks

Hi Tom and welcome to IRV2. I posted my question in the "other" forum but perhaps you missed it.
I have a 3000 MH transmission in my 08 Camelot and will have both the filters changed at this years service. The S/N of the transmission is 6510726660 and has 100% TranSynd oil with the high capacity filters. The filter kits I've located online are P/N 29548987 for the 2" filter kit and P/N 29548988 for the 4" filter kit. Are these the correct kits for my transmission?

Colemole,

DEXRON-III is not an issue at 25,000 mile drain intervals. DEXRON-III will lose viscosity over 25,000 miles but not to the point where you'll see much wear. If you'd like to get much longer drain intervals, then switch it to TranSynd at the next scheduled change. I firmly believe you'll be much better off in the long run.

PS: There's no way they knew it was DEXRON-III coming in the door. Id' ask them how they knew it was DEXRON-III. They would have had to do an oil analysis and would have had to know what to look for (basically low viscosity). My bet is that it was "red" so they figured it was DEXRON-III. Don't be fooled by these guys who do a taste and smell test and think they are giving you scientific proof. Only oil analysis can be used to properly assess transmission fluids, engine oils, differential oils, generator oils, etc.

Hey Tom, Can you tell us the best place to send fluid for analysis? Bruce

BigSkyBob,

I believe those numbers are correct for the "High Capacity" filters.

that pretty much sums up to use what they recommend for filters
thanks
