Time to change oil in my allison 644. It used to be that we looked for a C-4/ dex2 or 3. Now Allison wants everyone to buy Transynd, which is rather expensive. I have read where the military uses a 15w40, C-4 oil like Rotella T3. I have also heard of using 30w drive train oil, or hydraulic/transmission oil. I was wondering what others here are using. Thanks | ||

I always used CAT TDTO 10w oil in the 740 good enough for a $35,000 Cat transmission was ok for me never had a problem with one using it over the years. Cat also sells a synthetic blend that is good oil. The Transynd is a must for the World Transmissions but I wouldn't spend that type money for oil in a 644 it takes 2 changes good luck | ||

Thanks- It seems some are happy with regular Dex III. I do like the idea of the TDTO except I just looked up the temp range for the 10 and 30 wts, and they are rather low. The multigrade (TDTO-TMS)is rated to about 110 degrees though. Any reason that wouldn't work? | ||

Yeah, Although the chart was in C, I did a rough switch to F. Unless I am missing something, it looks like the F numbers are -4 to 50 for 10w, 32 to 95 for 30w, and -4 to 109.4 for TMS. Here's the link I got http://docs.google.com/viewer?a=v&q=cache:9jrsP0K1C9UJ:www.cat.com/cda/files/1386248/7/PEH P8035-02.pdf+caterpillar+tdto+oil+temperature+range&hl=en&gl=us&pid=bl&srcid=ADGEESjyNjLmV hNU5-GsBAN2VQTal-Bmt0bFhvVe7q1EKSgcvwXXAMlyw1Itr-29x4S67e0SufOSsqTrWs2_xK7ykAtf94Gq_yBfFvz jCLNVxGkOOC4Nu6XvwJ2Pv2UJvvGltDCvuzdJ&sig=AHIEtbSt8NTn77mwP8pgqev0hcKkFqV6Pg | ||

Moe, I can't access your link, but those temp ranges look like they are meant for ambient air temps, not oil temps. | ||

Sorry if I was not clear. They are ambient air temps as you say, but isn't that critical too? | ||

The Detroit shop did a complete flush and filter change on mine so i did not have to do a second change. The initial cost to change over is more but the savings comes from the increased service interval. Cheaper in the long run. | ||

Paul, the 740 shifts the best with 15/40 C-4,I have always used Cat Fluid it is the same as Delo 100- 10W those transmissions run a million miles on DEX or other fluids all the hype about Transynd I never bought into for 740 after all they get about 300,000 from the world transmission using Transynd wonder what they would not using it lol.7 or 8 gals at 10 bucks a qt naw not this one |
