Is Transynd really up to $60/gallon? That's what I'm seeing after a brief online search. That's approaching $500 in fluid alone for complete changeover of my current Dexron. Has anyone recently found a source offering any kind of discount?
Thanks,
Eric

Eric,
I think that a service on your transmission will only take about 7 gallons. The last TranSynd that I purchased was about 2 years ago in Texas, and it was $30 a gallon.

Thanks, Gerald. Yes, I was counting on about 7.5 gallons, so would need to buy 8. I saw that $30/gallon number kicked around a number of times on the forum, but I'm not finding it anywhere near that price shopping online. I'll keep on searching...

When I bought some last year I think it was 38/gall with the best price at the Allison dealer.

Thanks for the tip on trying a dealer. I generally seem to find dealer pricing high so hadn't checked with them. Just checked my closest Allison distributor in Sacramento, and they're price is $46.43/gallon. Their filter kit was also less expensive than I had been able to find online.
I'd like to use the method Gerald has written up to get more Transynd into the unit. Someone else had previously asked which line was the one to remove for draining, but I never saw an answer. However, on the bottom surface of the sump casting I see cast in features below the cooling lines. Looks like they may be indicating fluid flow direction, but I'd better make sure. I'm assuming the arrow head shape facing away from the sump is showing the line out to the cooler, and the other is an incoming "V" shape for the incoming line from the cooler. Is that correct, so I'd remove the incoming "V" line to drain the old Dexron until I see the new Transynd running clear?

I just paid $48/gallon at a United Truck Center in So. CA.

I assume that everyone realizes that conversion to Transynd requires a double fill-drain-fill procedure and that these quantities include that extra step? I think they do, but mine had been switched before I bought it so I can't be sure.
-
If Gerald's method (pumping converter and cooler after the gravity drain) replaces about 27 quarts of the 29 quart capacity, that would yield about a 93% Transynd blend. Is a second exchange necessary according to Allison? What is their stated concentration of Transynd to use their extended service period?
-
Eric,
If you can get a 93% fluid changeover, you are good for the extended fluid change interval.

I think I paid $43 a gallon at a big truck garage in Tampa, Fl when I did ours.

Does anybody have their transmission fluid tested yearly to determine when to have it changed rather than a set miles or time period? Is that appropriate?

Mine came with Transynd and always runs below 180 degrees. Because a couple of BAC members have had engine coolant invade the transmission, I've decided to start routine testing. But, even if the lab picks it up, it would probably be too late.
