Find a place for the plug that is clear of obstructions inside the
pan and is flat . Drill a hole that your plug will pass through and
screw a jam nut onto the plug and weld it to the inside of the pan.
After the weld cools, remove the plug and put the gasket on the plug and tighten it. Change filter, install pan, fill with fluid. I use SBC oil pan plugs (about $2.00) and
I get the jam nuts from my local farm or hardware store (under
$1.00)

You can buy the drain plug from B&M, It should be at any Pep Boys, Discount Auto. Find a location on the pan where the plug won't interfear with the valve body, drill a hole the same size as the hollow bolt,tightn' the nuts.

Aside from the valve body, make sure it isn't going to be under the filter when everything goes back together.

WASP - yeah, but what about reduced ground clearance with the TCI pan - there isn't a whole lot with the stock pan.

No offroading - at least not intentionally

I am more thinking about speed bumps and the like where the wheels front and back are on the pavement and the xmission would be coming real close to the bump, also going in and out of parking lots with pretty steep entrance/exits. Several of these spots I have to be REAL careful with the stock exhaust around the area of the xmission. If you, or someone else has had experience with this pan and found clearance not to be a problem under the conditions I have described, I would like to hear about it.

Be carefull! I screwed up a good pan by installing a drain plug in the wrong spot. The Only real good spot to install the drain plug is on the drivers side rear, 2in in 1/2in up from the rear. Yes it does reduce ground clearance but the plug will only hit if the car gets high centered but I think you would be more worried about damage to the GFX rather than the drain plug

Reduced ground clearance? Why are you putting the drain in the bottom of the pan?

It isn't the drain plug clearance that was the issue, it was the above mentioned aftermarket deeper xmission pan that I was concerned about clearance with.

Drain plug clearance INSIDE the pan is an issue.

the 4L60E should be the same pan. If so there is a GM deep pan that holds 2 extra quarts, + a factory drain plug. I just ordered 1 from GM.

Also be aware that aluminum cracks when hit, unlike steel which will only take a ding. --Now think about that when driving down a dirt road.

BTW: I'm also getting a one for my 4L60E also probably aluminum and yes I live on a dirt road I'm just going to drive real slow at least I'll try

that's why I recommened the GM pan. It is steel, has a built in drain plug, and holds 2 extra quarts. and then I use the extended GM filter kit.

Larry Burd - Thanks for the info on the GM pan, didn't know about that!

ronterry- good point about the aluminum

Board seems pretty flaky last couple of days, having trouble getting this to post.

Larry I might be looking into getting one of those GM pans.
How much, and are you ordering it through a website, or local dealer ?

I have put a plug in atleast 3 trans pan and I couldn't get the B&M one to stop leaking in all of the pans you should go ahead and get the tci pan so you dont have to under coat the car with trans fluid ...

drain plug

It seems the problem in my case was 2 nylon washers that go between the pan and the plug that is were it was leaking for me I may have over tightened a little to much .

Over here in Dallas we have this Road called beltline that I consider off roading. The right lane which is closed is about two feet higher then the left lane. Since its close the traffic from the right lane merges together in the center which is one big *** slope so your whole car feels like its going to flip. then up on the road ahead is a big blob of cement that sticks up about a little less then a foot from the ground. That sob will take your oil pan right off for ya. You have no other way around it either since there is only one cracked out road. This kind of construction goes on for 3 miles. There is a tractor or some construction vehicle every 50 feet or so. Now thats off roading. Never took my car down that road, dont think she would make it.

# 24215535 is the deep GM pan with recessed drain plug
#24208576 is the extended filter kit

The pan is deeper, so I recommend ckecking ground clearance. However I don't think it will be a problem. I have the pan and filter kit sitting right here in my living room
There is a magnet on it too. THis info is in the GM performance manual.

Cost me $100 for both. I will sell both if someone wants it immediately. I don't have plans to install it until the summer, so I can always order another one.
