A friend with an Model 10 Eagle w/ series 60 and Allison need a tranny filter. Anyone have a guess to the proper filter?
Thanks
Mark
I believe its an HT740. The owner tried to get it serviced twice but the shops didnt have the correct filters. Now it wont go into gear unless its rev'd up. He was also told 100k miles between services. He was told the filter and housing were 'antiquated'
The 740 has a washable screen inside the pan and should have 2 external filters that are easy to get at NAPA,they use so many different housings just match the filter and service the 740 at 25,000 to 50,000 miles depending on the fluid type

Thanks Cliff! I havent seen the tranny yet, he'll be here tom'w. I'm going on what Im being told. Cleaning a screen should be easy. And external filters easier. Lets hope its a 740. Not sure what else it could be.
LOL watch the 7 gals of oil overhead it can be nasty,he may have a B500 behind the series 60 and the filter upgrade was never done the old filters on a B500 are a PITA to locate
Havent seen the tranny yet but the owner says it has no external filters. And it has 100k on the oil and filter.
Mark if this is Ian's Bird, it is a 740 ;)

Hey Van! You guessed it. We cant seem to identify the tranny. I was trying to pick up filters for it today. He's in Boston today, we're heading in to see his show tonight, then spend a few days turning wrenches at my house.
As you know, he has to rev it up to get it into gear. Tonight is the last show on the tour and all he has to do it drop off the band in NYC. That boy is always livin' on the edge!!
So its got a cartridge filter! Any guesses?

mine is a spin on... the only sure thing you can do is start at the trans oil cooler and follow the hose... should lead to the filter.
The filter should be a Wix 51623 but people change bases so you never can be sure

Thanks Cliff! I'll see if I can pick up that filter tomw. Hopefully we can get him back on the road asap.
or NAPA 1623 but mine is a MT644 I just changed it.
Simple-if the two filters are built into the oil pan, it is a B500. If the transmission has a deep steel pan, most likely a HT740. I know on both the HT740 and V730, I use the same spin on filter which is a hydraulic filter. Good Luck, TomC
I got the chance to get under the bus tonight. It's definitely a HT740 but it's got a filter setup that I've never seen before..... and evidently the two Allison dealers it's been to haven't seen before either.
I didn't take a picture of the filter itself, but it's a replaceable metal screen filter that looks much like a fuel sock filter, but made out of a fine metal mesh. The tranny was rebuilt by WW Williams. SN 2775502106, PN 029508866, it has 6ALR on the tag as well. I called the local Allison dealer and he eventually found service bulletin SIL 12-TR-93 Rev C dated March 2016 and believes the right filter number is 29510918 which supersedes pn 23040988. No dealer has it in stock, Allison direct only, 5-7 days, $160. The filter canister says replace every 6 months or test with "electric method". There is only one filter on this thing, too.
I'll call Williams tom'w and see if they have info on it.
The last 29510918 filter I purchased was from United Transmission Xchange in Riverside Ca,since they dropped out of the Allison network they may not stock it now,Penske will probably have it in Cerritos Ca it was widely used on the remote mount 740's
United Transmission in Riverside, Ca did the rebuild on my V730. Good job and it handles the 375hp and 1125 torque of my turbo'd 8V-71 just fine.
You might think of just removing that obsolete filter and replacing with a spin on hydraulic filter. Both my V730 and HT740 have a single spin on hydraulic filter. Good Luck, TomC

Williams parts guy remembered that some of their older rebuilds had mesh steel filter remotely mounted on the side. He looked up the rebuild sheet and gave me a NAPA part number 7407. I odered one today and will know tonight if its the right one.
Upgrading to a modern spin on setup is in the near future.
Yep Wix 57407 or Napa 7407 I found one in the shop while looking for you invoice from 5 years ago lol was $32.45 with taxes
Napa 7407 is the correct filter. Allison wants $160 for it. I paid $36 at one Napa and we found a second at a different Napa for $48. Tranny shifts great now with new filters and fluid. We even put on new belts. Ian is on the road again!
Thanks for everyones input. Hopefully someone can find this thread and the part number if they ever encounter this oddball filter setup
