wildebill308 Report post Posted October 12, 2017 Welcome to the forum. I would use nothing but Transynd. http://www.allisontransmission.com/parts-service/approved-fluids Go here and register your transmission (you need the serial number) you can find out lots of info on your transmission. http://www.allisontransmission.com/parts-service/my-transmission Bill Share this post Link to post Share on other sites

redandsilver Report post Posted October 12, 2017 I used MOBIL DELVAC Synthetic ATF which is Allison TES-295 approved and on their list as OK to use and was more readily available at the time I was ready to do my fluid and filter change. Share this post Link to post Share on other sites
abyrd Report post Posted October 12, 2017 How often do you change you Allison 3000 filters? Can you change the filters without draining the fluid? Jim Share this post Link to post Share on other sites

Jim http://www.allisontransmission.com/parts-service/fluid-filter-calculator And, yes, you can change filters and will loose a couple of quarts, not whole 19 qts (3000 oil and filter change quantity). But, since the labor is virtually the same, not sure I would do it that way. Share this post Link to post Share on other sites
abyrd Report post Posted October 12, 2017 Brett., I have TranSynd fluid, thought it was good for extended mileage. I purchased the rig 6 years ago with 29,000 miles, I now have 55,000 miles. I have no record when the fluid or filter were last changed. I tried the mileage calculator but it didn't seem to apply to RV trips, you had to enter miles per day, hours per day and days per week to get a calculation. Thanks for the response.

Jim Jim, With that one (important) sentence, were it mine, I would change fluid and filters. Least expensive is a "pail" of Transynd (5 gallons). That will leave you one quart left over from changing a 3000 series transmission. And then an Allison (not Chinese knockoff) filter pack. Over the years, at least in the Houston metro, I have found that the Allison dealer (Stewart and Stevenson) is the least expensive. Compared with the cost of a transmission, cost of new fluid and filters is noise level. Share this post Link to post Share on other sites
abyrd Report post Posted October 12, 2017 We don't have Stewart & Stevenson in the Pacific NW, the closest Allison service is Western Star in Ridgefield, WA their quote is $480, it that in the ballpark? Jim Share this post Link to post Share on other sites
wolfe10 Report post Posted October 12, 2017 If that is parts and labor, that is not unreasonable. If parts only, might be worth shopping. Share this post Link to post Share on other sites

Jim I spent about $250 on 5 gallons of fluid and about $70 on the 2 filters - So about $320 to do it myself. Most time consuming part was the gasket removal using plastic scrapers instead of any metal to keep from marking up the aluminum covers that the filters attach to. Drained into a big tray and then refilled the gallon bottles with the used fluid and took it to a recycle center. It's not too bad of a job and I cleaned everything real good so I could tell if there where any leaks - none found. Share this post Link to post Share on other sites

Also use a good torque wrench on the bolts. Be very carful to not exceed the listed torque. Bill Share this post Link to post Share on other sites
