Anyone ever do an oil analysis on Transynd? I'm going to change the spin-on filter tomorrow and was thinking about sending in a sample, mainly to see how much longer to run it. I have looked up what Allison says I can run the fluid for, just wondering what it's actually got left.

Dropped the pan at 176,000 when the transjo jr went in. Changed both filters then and fresh fluid. Changed the spin on every 15,000. So I have 45,000 miles on the fluid now.

Any thoughts?

post office finally delivered the sample. 3 weeks to go 100 miles.


Anyway, came back good. shouldnt have any trouble running the fluid for 75,000 miles.

I'll post the report later. Taking a stress break now, I've had enough snow. Lets fast forward to May.

I could have answered your questions. 15K is too long to wait on the spin on.

:confused::confused::confused:

I was going off Allison web site maint. calc that told me 50,000 miles for the spin on filter was recommend!

I went crazy after the first 15,000 and said for the cost of the filter I'm doing it every 15K.



Allison calc says for my truck:

100% transsynd

severe duty

annual hours :1560/annual miles 87,360/avg speed 56mph (all very close to my truck)

change fluid : 75,000 miles

change spin on 50,000 miles

internal filter only at overhaul.



I've changed the internal twice, when I switched to the alli deep pan and when I did the transgo jr. Changed the spin on every 15K. I'd have to check the records, but I think I've changed the fluid 3 or 4 times.
