Allison Trans
I do most of my own work on the bus,when I first got it I had valves adjusted and trans serviced 3 1/2 years ago on their work order for trans service it says for fluid ALL27101-CTDR, looking at Internet looks like they used this fluid CTDR looks like it came out of a 55 gallon drum and it was $49.28 a gallon total price for fluid $ 320.32 that’s like 6.5 gallons and they have filters on there also ALL2958117 filter kit. Is that good trans fluid to use ? and 6.5 gallons is that correct?? That’s why I do my own work so I know. Can’t call them they closed last year. This picture on Amazon is 27101-CTCS must mean 1 gallon?

Transynd or its equivalent specification is what needs to be used in the Allison six speed. Also drop and change the filters, making absolutely certain the bolts holding the filters are properly torqued.
Whenever I change mine (with filters) it uses about 7 gallons and the best way to verify the fill level is using the touch pad.

Allison recommends using an Allison approved TES295 atf. There are 12 of them. Here’s a list: LINKThe torque specs are on a piece of paper in Allison filter kit # 29558117.The man that created the TES295 spec is Tom Johnson. He worked for Allison/GM for 20+ yrs. He is part owner a fluid analysis company, JG Lubricant Services, 877-971-7799 ext# 2. Here’s a link: LINKWhen you get your results, call and talk to Tom/Mr.Transyd himself, everything you ever wanted to know about your Allison and/or ATF.I run Allison approved Mobil Delvac 1 atf because I can find it at a much better price than the others.
