Vic Roma Posted July 20, 2021 Share Posted July 20, 2021 This might well be the dumb question of the day, but do our transmissions have filters, and is there reference to them in the parts catalog? I can neither find an illustration, nor a line entry for it in the text, specifically 70.9B which I believe is my list for the 84 4x4 U150. Although it could also mean instead of a magnifying glass, I need a telescope. I am hoping it's just not in there. Link to comment Share on other sites More sharing options...
grumpin Posted July 20, 2021 Share Posted July 20, 2021 Yes. http://www.garysgaragemahal.com/c6.html 7A098 Assuming you have a C6. Edit: I see you have an AOD. That should be in there too. Link to comment Share on other sites More sharing options...
Gary Lewis Posted July 20, 2021 Share Posted July 20, 2021 Yes, the automatics have filters. But I'm confused about the "70.9B" that you said is your parts list. I can't find that parts list in the MPC, nor any mention of 70.9. But I did find this table which shows the designations for each automatic tranny and I don't see a 70.9. What am I missing? What transmission are you working on?

I took my reference from this page in Section 70 (see below). There are 17 bolts securing the pan, so does this automatically make the trans a C6? It does according to one website I read comparing C4/5/6. Link to comment Share on other sites More sharing options...
