Transmission Service
I plan on having the transmission fluid and filter changed on my Chevy D/A. Will probably take it to the dealer if I can't find a local garage to do it. Generally speaking, about how much does somet...

I have an 05' and Allison does not reccommend a flush. If you have an Allison dealer near you you can buy Transynd for alittle over $30 a gallon and a spin on filter for about $9.00. Allison has a drain plug so it's no problem to change. You don't drop the pan for the internal filter unless you are doing an overhaul. Drive for 10,000 miles and repeat and Allison considers this to be a complete switchover to synthetic. You will notice smoother shifts and lower temps. It takes alittle over two gallons for the exchange and fill the spin on before you put it on. I change my spin on every other oil change. Cheap insurance for an expensive transmission. This is just what I do. I'm not saying it's by the book, but from being on the diesel forums it is usually an accepted maintainence schedule.
Did the same double drain and fill on my previous '06 LBZ with Transynd. Local Allison dealer charges %45/gallon. I also agree that Allison does not recommend a flush. I change the engine oil every 7500 miles and replace the transmission filter and top off every 15,000. Be sure that the magnet does not get thrown away when the filter is replaced. Be aware of $9.00/transmission filters even if they are red. That filter is probably Chinese. (Edit to say that $9.00 filter is not necessarilly Chinese but I have seen them.) Go to the Class A Motorhome forun on RV.net and read the post "Let Me Know if You Have Allison Transmission Fluid Questions". That guy is THE expert on Allison and Transynd, I just "BUMPED" it to bring it up again. The posters name is "hzjcm8"
