02 C5 Convert....Auto Trans - Pretty much stock at this point.

Just thought I would let everyone know, I switched to Mobile 1 Full Syn ATF when I did a fluid/filter change this past weekend and it dropped my temp 10 degrees. I normally ran at 208 and now I'm not getting above 198. I'm adding a trans cooler here soon too.

Has anyone ran just the deeper pan? What were the REAL benefits you got out of it. I was thinking about it in addition to the trans cooler but wanted to see if anyone had real stats on it before I dropped the cash on it.

Thoughts???

 

Why do you need a trans cooler?

 

because for every degree you lower your trans temp is that much longer your trans will last. Don't quote me on it...but I think the stats were for every 10 degrees lower in operating temp your trans will last you twice as long. Heat is the enemy of your trans. I know 208 is not bad at all, but through days of research everything I've read says if you can get your temp to operate between 180 and 195 is optimal conditions for your trans to last a long time.

Not only that but I live in Texas where heat is my biggest enemy! LOL

 

I understand the benefits of a trans cooler, and I also see the need for those that auto-x their cars, or those that tow trailers, but for a daily driver with no mods......?

 

Then you missed the key word....."pretty much stock AT THIS POINT", you have to start somewhere!

but does it really matter? I was sharing my info and was asking for opinions on the deeper pan and wasn't seeking crit on the path I choose to mod my car. The title wasn't "what do you think about adding a cooler to a stock vet". Is this how you treat all the new people??? You're smart and we're idiots because we're not inline with what you feel is "RIGHT"? Maybe I need to rethink my membership here.

So are there any useful opinions on the deeper pan???

 

Wow....Okay..A lot of new C5 guys start modding their cars with things they don't really need. I try to take a look at one's sig, to see how their car is currently modified. Many forum members on here have saved many guys money when it comes to mods....because they know what the really need and what they don't. While a trans cooler is relatively inexpensive, and will certainly lower temps, I find it a stretch on a stock car, or even lightly modded car for that matter.

Welcome to the forum..........nice tude....

 

Ok...but what you AREN"T taking into account is the fact that I live in a place where 110 degrees all summer long is normal. I live in the Hill Country and traffic is a factor. So temp 110+, driving through hills, and sitting in traffic.....$70 to protect my car better, why woudn't you encourage me??? If I lived in IL, I wouldn't even think about it; but heat is a real issue here even for non-mod cars. Then even stock wanting to take it to the Grand Prix track here and have some fun.....its called cheap insurance. and then adding mods, it will only benefit.

Try reading the WHOLE picture if you wanting to look at pictures before making someone feel stupid for asking a question.

My attitude is fine and I'm a really nice guy and very easy to get along with, but when someone starts acting high and mighty and a know it all that about something that wasn't even teh question I posted, that sort of rubs me the wrong way. Should I ask your opinion before buying any mods???? Sorry, I've been building and modding cars since I was a kid and I beleive strongly in protecting what you have before just adding tons of raw hp.

maybe you should rethink the whole idea of "Helping" people save money on mods unless an opion is asked if they should do the mod or not because honestly, it only comes across as a know it all that can't figure it out why someone would do something that isn't inline with their plans. Not everyone is going to mod their cars the same way or else everyone would have the same cars.

Thanks for your opinion but I have my reasons.

Now again, does anyone have any OPINIONS or STATS on running a deeper Trans Pan that would benefit this conversation?

 

Take your meds bro.....

 

how about you pat your self on the back for successfully running a new member that just joined TODAY.

Guess I should ask you if it logical or not for me to tint my windows?????

 

10 degrees from oil only is really good. and i support your idea of having a longer life for the trans.

ill be searching for the same oil that you used. How many liters did you get fro mthe trans? thanks for the tip

and yeah im adding a trans cooler as i live in a place thats very similar to texas..heat is my enemey as well

 

Ok...maybe I was being a little harsh, sorry rough day at work and that just rubbed me the wrong way because the logic behind not spending $70 no matter where you live to make your ride last longer was just blowing my mind.......

Ok..took some Excedrine and got rid of my bad head ache, and I applogize if I took anything wrong, but that's the way it came across to me.


I got the Mobile 1 Full Synthetic ATF fluid but you need to do a little research as there are some years (mainly the newer ones) that are not suited for this ATF. It says all 2005 and earlier can run the M1 Syn ATF.

Of course the true test is going to be next summer!

I bought 5qts of it, but it only held 4.

I've been thinking about adding the deeper pan too that holds an additional 4 qts over standard but I was wanting to see if anyone else was doing it to see what kind of benefit they were getting from it. I couldn't find any hard data on it and didn't want to spend $200+ for a new pan + 4 additional qts at $8each for 3 or 4 degree difference.

I'm running a finned deep aluminum pan that holds 4 extra quarts.
Summer driving A4 temperatures are 15 degees lower after I installed it.
The pan fits perfect, and has high quality casting and machining.
Heres a link to it. Welcome to the Forum!

I think its a good idea, the trans on the C5 is buried up in the back of the car, without the air cooling that a front mounted trans gets. Thats why the factory offered rear differential and trans cooler systems in the perf parts catalog for C5's, extra unwanted heat. I would be sure the deep pan did not reduce a critical ground clearance point though, just a thought, the C5 is pretty smooth and low at most points.

 

This was also one of my concerns when I was choosing a deep pan.

As it turned out, the bottom of the deep pan sits well above the fuel tank shields and exhaust pipe flanges.

 

Thanks....not this is info I can use! I would have to be inclined to think that with the trans pan back snugly between the tail pipes that it has to be getting less air flow and added heat from the tail pipes too, but it all seems to work anyways.

 

I would still add a trans cooler as well into the system. The bigger pan is a very good idea given if the clearance works which it sounds like... For the fluid I haven't used the mobil 1 syn atf.. but I have had the best luck with amsoil, I have seen it lower temps for my customers that road race. Good luck with your future mods!

The cooling fins that are cast into the pan bottom add some additional surface area, which also helps to dissipate heat.

After seeing good results with the deep aluminum pan on my Vette,
I also installed them on my Silverado and my wife's Blazer.

As a side note, I'm using GM Dexron VI fluid in them all.

 

A deeper pan isnt just about heat. Since there is more oil, the oil wont deteriorate as fast. Also good for high G loads with a lower pickup in the pan so you wont get starvation.

 

Glad you settled down, you may want to send a PM to Lucky.

Anyway, I'd suggest getting a DeWitts radiator rather than a secondary cooler or deep pan. Nothing really wrong with a deep pan or a secondary cooler. But a big race radiator will help in ways the others can not. Not only will it help with coolant temps, it will help with trans temps. I liked mine a LOT better than putting on a secondary cooler on the trans.

Also, IMO the traditional idea of a low temp adding a lot of life to a trans was true back in the day. But, with modern fluids, components, and controls, lowing the temp won't help out as much as it use to. The over heating warning won't even come on until like 255 or 260., and you won't see that unless you autox or road race on a track.

Lastly, the exhaust pipes are not very hot by the time they reach the trans. I wraped my pipes, but then took it back off after a year, didn't help. So don't worry about that so much.
