Re: Transmission drain / Change to Allison synthetic fluid and Allison filters Reply #25 – December 18, 2017, 11:19:56 am Mike,You can help insure a "clean job" by cleaning the bottom of the transmission, particularly around the drain plug and two filter caps. An old kitchen brush Dawn and water work just fine. Many techs do not take the time to clean before opening the transmission.And, cheapest way to buy Transynd is to buy a 5 gallon pail (a very common Allison PN). Pick up an old one gallon Transynd jug (plenty lying around any Allison shop) and pour 1 quart into it. Then the 19 quarts left in the pail is the proper change quantity for your transmission.

Re: Transmission drain / Change to Allison synthetic fluid and Allison filters Reply #28 – December 18, 2017, 10:28:06 pm Bob, mine comes on at 250º, but that is on the dash gauge. The VMSPC retarder temperature gauge would have been up close to 300º or just above by then and averaging in the mid to high 200º's for awhile as in going down a long steep grade for awhile without downshifting at the 4th or 5th notch. I also have the trans temperature on a VMSPC gauge that corresponds to the dash gauge, but that is not the retarder fluid sensor, it is reading the trans fluid temperature in the sump.DonQuote from: Caflashbob – December 18, 2017, 08:48:24 pmDon my trans warning buzzer comes on at 250 on Vpms Quote Selected
