Fluid change for Allison 3000 transmission
Just had my Allison 3000 transmission changed W/ new filters . The mechanic used Valvoline DEX VI ATF fluid. A full synthetic fluid. My question is will this fluid be OK for the Allison trans.
Forum Discussion
Yes, there are two different change intervals recommended by Allison depending on what fluid is used.
ABSOLUTELY, verify:
1. The fluid used is OK for the transmission.
2. Whether the fluid used qualifies for the extended service interval suggested for Transynd (or its equivalent).
For Allison 3000 series, I always use the Allison filter pack (PN depends on sump depth-- that are two different ones) and a 5 gallon pail of Transynd. Change takes 19 quarts, no that leaves you one quart left over. Just pour old fluid into the pail and take in for recycling.
