Job 1 Auto Trans question

[HM-8404]

I have a job 1 w/auto trans. I understand these have an external filter. Is the filter what I see at the front of the transmission mounted horizontally on the bottom?

you can have 1 of two external filters

one is near the bottom of the transmission bell housing the older style is up by the radiator

you can also change pans and upgrade

I saw something near the bottom of the bell housing mounted horizontally with two steel(?) lines attached on the drivers side. I assumed that was it but was not sure.

One more question... After searching this forum I have not found a clear consensus on what to use, Mercon LV or SP on my truck. I am going to have a local shop do a flush and fill. He does great work but I am not sure if he is very familiar with my trans so I want to help him out all I can.

[ZMANN]

SP is discontinued so He will likely use LV

make sure He uses one of those 2 however as they are mixable but it's a picky transmission so don't let Him use a universal unless its Valvoline and the right one at that

now make sure He has a OEM or compatible filter on hand since that was a low production unit

checking your PM now

Just be ready for sticker shock too. I had that filter changed a while back and if im thinking right it was around 150 ish.

you can get it on amazon for 80ish. or rock auto as well.

7C3Z-7B155-B / Motorcraft FT-176 is the part number, I had one on my truck. I recently had my local shop install a spin on adapter where the external filter was so he was able to remove the external filter and replace it with a block of aluminum that now accepts a allison spin on filter that costs around $10.

08smoker08, Do you happen to know the thread size on the filter lines? And did they just use adapters to change the lines into something that would fit the new style filter head? If you could post a pic that would be great!!

[ZMANN]

if it were mine i would find a way to bypass that filter altogether and put the late
08 pan ( or monster Derale pan ) and Fram ( is OEM) filter on there for 100% filtration vs the cooler bypass filtration

but the Allison mod is second best,,, very creative

I'm surprised nobody has come out with a conversion kit yet, or at least short lines to put in place of the external filter. That would be much easier and cost effective than replacing the line sets. Then could just install those, replace pan, and internal filter. Maybe because this set up was so limited there are not that many out there?

BTW... I noticed my trans fluid has a very rusty look to it. Looks like I may have water in trans. That's just great!! I'm not in a position to replace radiator and rebuild trans at the moment. Thank you IRS! Getting a new trans is out of the question right now. I have no shifting problems at the moment. Maybe it will hold together for a couple of months. I can hope anyway.
