Read and reread posts on transmission fluid and filters . Intend to get my non-synthetic ( I think ) fluid changed whilst in Las Vegas at an Allison shop , should I ring ahead and ask them to supply filters or should I go to Napa and purchase before we set off ? Also any idea on latest non synthetic filter kit number

All the Allison filters are the same whether syn or not to the best of my knowledge and I have done it many times with various coach's.
The Allison shop will have them and I would leave it up to them to supply not Napa.

I know this is a divided subject but why would you not use Transynd?Most trans failures are heat related,the synthetics cut down on
heat.

Would be shocked if your coach did not come with Transynd from the factory. And, I would use Allison only filters.

+1 on Allison Filters, Brett

I recall 1999 or 2000 as being the year that Allison changed their policy on Transynd in Motorhome applications. Seems to me there was a bulletin from Foretravel in about 2000. I know our U270 did not come with Transynd in 1998 and I recall our running mates (2000, U320) changing over to Transynd in 2001 or 2.

Edit: FT Bulletin, 8/26/02. "The first 2003 models off the production line will have initial transmission fill with Transynd." It's in Barry's information.

Looking through old invoices from PO I see a fluid and filters change with non synthetic. The dealer was supposed to change all fluid when I purchased coach.
Trying to chase that one .
Only thought is synthetic involves two changes at about $500 per change?

That's something you have to decide for you.

Just read some info on the Allison site dated from 2013,if using transynd for extended drain intervals they now recommend
the hi capacity filters over the gold.Hi capacity number,29548988.That's how I read it.

Based on recent experience - call ahead to check filter stock. Took 2 days to get mine in at Allison (S&S) shop.

Correct on the high capacity filters and and to me a no brainer in changing over to Transynd( even though I drained mine out and put in the Amsoil Torque Drive instead). The coach shifting is way better and heat a none issue now.
I am afraid that the extra cost of doing another drain (of around a gallon and filters) is a needed exercise and puts you miles ahead of the game as you may never have to do it again.

I thought it was a full drain and refill with filters at second change

Re: Transmission filters

Reply #11 – November 04, 2016, 02:10:53 pm

The first one is obviously a full drain (but will not get at the torque converter oil etc) along with filters and then at 25k another drain but only what comes out with filters which is around a gallon or so AND again filters. Just like I mentioned before.

When I changed the fluid and filters on our coach, found the Allison filters were cheaper than the napa filters. Your coach should have had transynd from the factory. Would go back with transynd and at the next time due for filters and fluid again use transynd and then most all of the non transynd fluid should be gone.

Just wanted to check, the filter kit listed is 29526898. But understand that there is a high capacity option 29548988 .
This is for the 3000 transmission

Had our 1994 Allison MD3060 transmission serviced with Transynd, new filters, and a flush (changing over from non synthetic) 9 days ago at Julian's Transmissions in Amarillo TX ( authorized Allison shop).

With tax included: $692.70.

Jimmy, that $1000.00 is a joke total rip off. The Transyd here in BC Canada is $50 gallon (cndn) and filters are $125(cndn) so work it out from there and we pay more for all things compared to you guys south of Border. I can do it all in about an hour or 2 max (drain and filters) and have done many times, so why that cost??

Most owners do a better job than most shops on this-- it is not technical.

What makes a difference:
Taking time to clean the bottom of the transmission before opening it up so no dirt is introduced.

Using an inch-lb torque wrench on the filter plate bolts. Steel into aluminum, so air wrenches are a no-no.

Allison filter kits come with complete instructions (at least did last time I bought one).

Be sure to only use the style of new gasket that matches what is on yours now-- they come with different styles to accommodate different transmissions.

Correct.

Brett, I have a feeling that Allison has now changed the requirement to only use the style (sq or O ring style) that is currently on your unit. I say this because a few weeks ago Geoff and I did their Trans' and oil and on his it had the square seals and the new(high Capacity) filter kit had only the round O rings. This filter kit was dated fairly new and upon asking the Allison place here they told me that this is the one to use now, so I guess that directive is now gone??? I did not see any leaks etc after job done so I guess it is ok.
