Well, I changed my tranny fluid and filter before this deployment, and couldnt get that thing to seal for the life of me. I tried three times, and it continued to puke tranny fluid, all over the exhaust.
This is due to the ****TY stamped pan.

First question is this. Im no where near my k5. Is there any clearence issues with a deep pan?

Also, ebay has a ton of NEW deep 700r4 pans for $40 shipped, or $17 + 20$ shipping. They are cast, so i assume the would seal better, but for that price, i have to question quality.

How tight were you getting the bolts? With a fresh gasket and lightly torqued bolts mine sealed up perfectly fine with the stock pan.
 
I'm not over tightening them. I just think that old pan is a little too warped in some spots. It most definently has been over tightened in the past. It is pulled down a little too much around every single bolt hole
 
I'm not a fan of aluminum pans since they will crack (and leak all your fluid) if they are accidently hit by something wheras a steel pan would just dent.

Wow. I totally havnt thought about that, and is now, a serious concern.
like i said, i cant glance under my k5 at the moment. Is there not a skid plate protecting it? I know the t-case has a little plate, but nothing for the tranny?
 
There is no protection for the trans pan. Now you could go ahead and build some sort of skid plate to protect it if you wanted to.
 
I'll have to disagree with Scott on this one... I'll take the superior mating surface and cooling of an alum pan ANYDAY over the potentiality of landing on a boulder, on your pan...

Here we go again. :rolleyes:

I agree that the pan will bring stability, better cooling and a far superior sealing than a steel pan will. I simply said that an aluminum pan will crack whereas a steel pan will dent. I also never said anything about "landing on a boulder". There are far more things that could crack a pan other than just "landing on a boulder". :deal: :D
 
dude, chill..... I tried to be as diplomatic as I could with that, and not offend you...

have you ever smashed your pan? I can find eleventy million posts in here about leaking pans, but have yet to hear of someone cracking an alum pan...

my opinion....
 
Both valid points gentlemen.
Seeing as how 700r4's hate to run hot, The added cooling of aluminum, as well as the added fluid capacity probably out weighs the risk.
AND! im no fabricator, but im pretty sure i could come up with a plate down there.

Most definitely something to be aware off... the cracking issue.

Now, another issue. With $40 including shipping, ive gotta question the quality. I mean, you cant really mess up a pan, unless the sealing surface isnt true and flat.
I really like the drain plug. It is beyond me why GM didnt put a plug in the pan, when the fluid level is above the seam.

Settle down, i put a smiley at the end for a reason. :D
 
Post back when you get it, I'm interested to see if its as thick of metal as the stock pan. If its good quality I'll be getting one. Do they use the stock filter?

Then you should see my pan. :D I run a steel B&M deep pan on my th400 and it is dented. IMO if your not going to put a skid under it and wheel on the rocks then get a steel pan. If your doing mild wheeling and not going to hit big rocks or your going to make a skid then go aluminum.
 
I bought one of the ebay aluminum pans and it is pretty damn thick.

There isnt a magnet inside though. I'd epoxy one to the bottom of the pan if you can. I didnt have time but need to back and do it.
 
Check to see of the pan is flat between the bolt holes. What typically happens is the pan gets high spots at the bolt holes from over tightening. You can check this with a short straight edge. If some of the holes are high spots, you can flatten them back out with a couple of ball peen hammers.

I’ve never had a problem with the aluminum pan with the exception of the above mentioned problem

That is without a doubt my problem. There was alot of wrong on this truck when i got it. Nothing crazy, just some real halfassed stuff. Finger tight intake bolts... and such. The pan rail is like a roller coaster. I could flatten it out for free, and have issues with it again over time,
or, i could spend a little coin, for better cooling, better sealing, and in the end, probably longer tranny life.
