Deep Pan Transmission Modification
Posted: Thu May 28, 2015 9:27 pm
So I did the Deep Pan Mod described very well over at CarModder.com:

Couple of things I ran Into. The GM bottles of Trans Fluid have a vent in them now so trying to use my fluid pump I was unable to center it in the hole and thus could not tighten down the pump on to the gallon container. Broke it trying, managed to git the fluid in. I guess have a clean gallon jug you can transfer the fluid into that will work with your pump or a different kind of fluid pump.
On Checking the fluid level after you fill it up there are a few issues that come up.
1. Getting the car level. I read the car has to be level so when you take out the fluid level plug it goes to the right level in the pan. Problem is it seems like you really have to get the transmission level (not the same thing as the car level. I guess when GM techs do this on a lift they just lift the entire car level and the trans is close enough to level. But to my eye the trans being level and the car being level are to different things. I could only get it so level with jack stands so going to try and check the level on a lift and see how that comes out.
2. So to check the final level you have to have the transmission temp up to operating temperature, have the car (or trans) level and pull the fill check plug and see if any fluid drains out. Fine enough. But if you have to add any fluid you have to pull the fill plug at the side of the trans and add more fluid. Well the only way to get to that plug is putting your hand right next to the exhaust. And just getting that plug out is hard enough without having to deal with a hot exhaust pipe.
This leads me to believe GM must have a tool to fill the transmission through the bottom level check hole. No way are techs putting their hands up the side of the trans next to the exhaust. So it would be nice if we could get our hands on something that would make it easier. Maybe just a small tube in the fill check hole could pump fluid in while still allowing some to escape when it is full. Gonna have to experiment with that.
Also came across that many guys are just adding an aftermarket flexible dip stick tube to make the filling easier. Ones they are using are from Lokar Industries at about $100.00 a pop. If it was $30.00 Maybe I would do that, but it's not that hard an operation to pump it in at the side fill hole.
I measured what came out at about 6 Quarts. So I know the new pan holds more so I just pumped in 7 quarts so I know there is enough in there for now till I can check it on a lift.

I am not much of a racer so I cannot tell any difference performance wise but I do like the idea of more fluid and a deeper submerged pick up point.
Ground Clearance was the other issue. Tried taking a few side shots to see if the pan came down below the rails. It does a bit in a certain spot but still not lower than the exhaust couplings hanging low. Would not recommend for a slammed car. But for most of us do not think it will cause any issues.
