Transmission pan

What is the best/easiest way to get to and then correctly torque the pan bolts that are right above the cross member/brace?

727 tranny

Just the regular transmission pan? On my 83 I was able to access all of the bolts without and issue. Is the gasket leaking?

It’s leaking enough to warrant a new gasket.

I’ll try and get a good picture.

Make sure you don’t overtighten the bolts either, that will cause a new gasket to leak as well.

@tripwire. Yep. That’s what I’m putting in.

so now that i'm over thinking everything...

Can anyone recommend a replacement pan with drain plug? there are tons out there.... I figure if i will have it off, may as well put a new one on with a plug so I don't have to do this every time.

thanks
Mike

I bought an after market plug where you drill a hole and install the drain plug.

Can you weld? Cut a pipe coupler in half and weld on. Install plug.

Mopar Part Number P3690730AB is a deep pan w/filter extension that fits our vehicles (w/727 TF) perfect. Mopar also has a reusable pan gasket that is really nice but unfortunately I do not have the p/n.

I have the Mopar steel deep pan - went in no problem, holds an extra couple quarts, and there's now a drain plug!

Will make the next filter change a long time from now a lot less messy.

10/10 would do again.

How much deeper are the Mopar pans? When I looked a few years back about installing a deeper pan it didn't look like I could get to the back bolts to tighten them.

It has been many years since I've installed the Mopar deep trans pan. I don't remember having any major problems installing it.

yes you will have bolt access issues, i notched my crossmember in one place and drilled a hole or two in others , also helps to have smallish hands

I've had the best luck by using a rubber gasket with either the ATF-specific Permatex sealant or Right Stuff on both sides and tightening the bolts to the torque specified in the manual. They seal perfectly for the next 30,000 miles before I crack the pan loose again.

There is a special place in hell for people who over-torque and warp transmission pans, engine oil pans, etc. If yours is warped, take the time now to flatten it back out with a planishing hammer.

Welp... I went ahead and ordered a new mopar pan. Looking at mine , it has plenty of surface rust. No big deal, but I figured the time to clean it up, fab up a drain, and repaint it I should just order one already with a drain plug.

@trip. How big of holes did you drill in the cross member? Ones to fit the socket or just a hole big enough to get an extension in (and have to put the socket on once it’s through). Drilling a 3/8” - 1/2” hole seems a lot easier than drilling a 3/4”+ hole.

Or maybe just change those back bolts to socket head cap screws and just need to have a hole big enough (with some room) to run an allen socket

I still don't remember having that hard of a time installing my deep pan. I guess it is possible I changed the trans mount too and maybe I took the cross-member off or maybe I just jacked up the rear of the trans.

Tripwire...How many of those great Mannys did you have before you decided to drill your cross-member? LOL! Seriously though, I would trust what Tripwire says.

I definitely didn't have any issues with getting at the bolts using the mopar steel pan. Was reading that some folks have to modify their crossmember using the B&M or other pans.

I think it gives you another quart? Wasn't really interested in the capacity increase so much, but had to replace the pan anyway & wanted a drain plug.

For the record, this is the one I bought, and it went into an '84 GW:
