HOrnbrod Posted February 9, 2018 Share Posted February 9, 2018 I've been corresponding for about a year now with PML (yourcovers.com) regarding a new deep pan they are coming out with for the AW4 / A340 auto transmissions, pictured below. Looks like I'll be one of the evaluation test pigs. Looking forward to it... Link to comment Share on other sites More sharing options...
Dzimm Posted February 9, 2018 Share Posted February 9, 2018 This is interesting and I'm surprised a company is just now making a product for these trans. I will be following your updates on this to see if it would offer any benefits going on a truck built for racing. I have a few questions for you that you may not be able to answer quite yet but I'll ask anyways. - What are the benefits of the deeper pan? - What do they expect it to do for the trans? - How do you use that fill hole that will be on the bottom side of the trans? - Is the pan itself thicker to withstand some impacts? - Do you know yet how far down it will hang?

HOrnbrod Posted February 9, 2018 Author Share Posted February 9, 2018 Most of those questions will be answered after you read their web page: https://www.yourcovers.com/transpan_11076.php Link to comment Share on other sites More sharing options...

Minuit Posted February 9, 2018 Share Posted February 9, 2018 Lack of a dipstick is a deal breaker for me but I understand why they got rid of it, and I hope it'll serve well for those who need it. Link to comment Share on other sites More sharing options...
Green Mesa XJ Posted February 9, 2018 Share Posted February 9, 2018 Real cool. I didn’t think of a side fill port replacing the dipstick. It’ll make maintenance easier, might miss the quick access for checking levels the dipstick provides, if I am honest I’d rather pull the plug and check the level. On later jeeps they don’t include dipsticks and the generic Mercedes style dipstick is a pain to read correctly I replaced the f150 and commanders oil pans with new ones that had drain plugs, if this were cheaper it’d be tempting.

I hear ya. I can never get an accurate reading with the tranny dip stick cold or hot. It's never clean-cut, always smears differently on both sides. Never could with any of the MJs and XJs I've had. At least with the level hole you can get it spot-on, even though it's kind of a PITA. Link to comment Share on other sites More sharing options...
ScottJeep Posted February 9, 2018 Share Posted February 9, 2018 Registered with them about a year or so ago. The dipstick was the one question I submitted with my inquiry. For all the above reasons. Link to comment Share on other sites More sharing options...
johnj92131 Posted February 9, 2018 Share Posted February 9, 2018 Don, Will you be doing any fluid temperature checking before and after installation of this pan? I "assume" temperature control is one of the main functional reasons for a finned deeper pan. John Link to comment Share on other sites More sharing options...

If this works out, I'll be drilling/tapping in a 1/8" NPT hole for the temp gauge sender on one of the pan bosses. Link to comment Share on other sites More sharing options...
johnj92131 Posted February 9, 2018 Share Posted February 9, 2018 Don, I know you are good about test data. What about data with stock pan before new pan. Care to share? Old data from Corvair aluminum oil pans showed oil pick up had to be lowered to get cooler oil at bottom of pan. Aside from higher pan capacity, doesn't improved oil cooler seem to make more sense? Good to see you in the test! Link to comment Share on other sites More sharing options...

Agreed. No dipstick = no dice What's horn supposed to do, empty it into a five gallon bucket and measure it with a table spoon as he fills it back up?

I run about 170-200 (~180 average) degree tranny temps now, and I'm expecting the alloy pan will drop these temps down 10-15 degrees minimum. It should with the increased fluid capacity and better airflow because there's more pan surface (1-1/4") in the airstream underneath. If that happens, I'm going to temporarily disconnect the wonky radiator "cooler" and it's leak-prone lines and see if the pan itself will be enough to keep the temps cool. I think it will. The goal is to eventually junk the tranny radiator cooler. This is still "several months out" according to PML, so we'll see what happens if/when it happens.

Minuit Posted February 10, 2018 Share Posted February 10, 2018 Don, are you still running the itty bitty factory auxiliary cooler? Or is that someone else I'm thinking of. Link to comment Share on other sites More sharing options...

You don't have it plumbed in through the cooler in the radiator too, or does your radiator straight up not have a cooler in it? Link to comment Share on other sites More sharing options...
HOrnbrod Posted February 10, 2018 Author Share Posted February 10, 2018 Yes, it's plumbed in series with the radiator cooler. using the return line. Link to comment Share on other sites More sharing options...
DirtyComanche Posted February 10, 2018 Share Posted February 10, 2018 Wait, I think I understand now, your plan is to junk the one in the radiator and continue to run the aux cooler, rather than to junk the cooling setup entirely and hope the pan alone does it? My XJ doesn't have the radiator cooler. The jury isn't out on if that was a bad idea or not. There's just a B&M cooler strapped to the front of the rad.

Yes. It'll clean it up and get all the hoses and fittings out of the engine bay. Link to comment Share on other sites More sharing options...
