Is the top line fluid exiting the trans and bottom returnin?
Does the exiting trans line connect to the top of the raditor line or the bottom?

Fluid comes out of the bottom trans fitting.

The bottom trans line goes to the bottom radiator line.

Top goes to the top.

I tought the line on the top of the stock cooler was the return line. Thats what I read on here and thats the line I put my cooler in.

edit: I just relized thats what the guy above me said.

It depends on the transmission. 4l60e, 4L65E, 4l70E, 700R4 all come out the bottom of the transmission. 4l80e, and all gm 6speeds come out the top. Ideally to cooler ooil should enter the bottom of the end tank cooler.

If they don't specify the answer defaults to stock LS1tech answers.

What.

With any fluid to fluid heat exchanger, the two fluids flow in opposite directions.

Radiator coolant flows down, trans cooler fluid flows up.

O.k. the original question was does the trans oil coming out of the transmission come out the top fitting or the bottom. In most applications trans oil flows into the bottom, unless it is a reverse flow system. but the oil out of the trans is a stated above does not change.

I'm still not getting the last parts of your posts, what does this mean?



My point is this. This is an LS1 site, no one ever gives specific details so I'll assume the guy has an LS1 4L60E.

Fluid comes out of the bottom fitting on the trans, you connect the bottom fitting on the trans to the bottom fitting on the radiator, now fluid is going to come out of the top fitting of the radiator, then you take that top fitting of the radiator and run it to the top fitting on the trans.

You can't explain it easier, but you can over explain it and list how every trans made flows and confuse the hell out of the OP.

I believe that if you look at the next ten postings there are references to 6l80E, 400, 4l80e ETc... so people with LS2 LS3 and LSx and Ls7 should not be posting here???

Thanks for yalls help! Sry I didnt specify....its a 4l60e I went from a4 to m6 and thought i was never goin back but now i just finished a m6 back to a4 swap so I wanted to make sure i had it rite

I just try to answer the question being asked.
Yes, I do see other questions about other transmissions, but they are in other posts, not this one.

But thats just me simple question---simple answer.

Anyone wonder why my user status says restricted? It's because of this post
A guy asks a question, I answer with a simple yes.

And no one understands, until the very end.

So maybe you are right, post all the info you've got because people will continue to misunderstand, take words out of context, not provide enough (if any) information, etc. And someone will get mad because you either went out of your way trying, or didn't type enough words and use enough cute little smilies.

i agree with above but i think most confusion is bc its not specified about which ends of the lines you are referring to and also even i didn't believe at first that the fluid actually traveled up.

Whats the temp diff. if hooked up incorrectly?

Okay, so on the 4L60E, it goes like this;
Out the lower port of the transmission, into the bottom port of the radiator/cooler, out the top port of the radiator/coolant, back into the top port of the 4L60E. Correct?

Now, what if you add an aftermarket tranny cooler, what should be the specific route?
Assumption: After it comes out of the top port of the radiator/cooler, it should go into the aftermarket cooler, (Lower port if mounted in that fashion.), out the top port of the aftermarket cooler, & then back to the top port of the transmission?

(Using the aftermarket cooler as a 'secondary' cooler?)

Most recommend bypassing the radiator cooler. But if you do install an auxillary cooler, most recommend splicing it into the line that exits the top of the radiator.

iTrader: (10)

I can't edit my posts, so I'll add this....most auxillary coolers don't have a specific inlet/outlet.

So it is best when installing a 20K BTU cooler to forgo the stock radiator piec and just run the 20K?

9000th01ss

iTrader: (10)

Whatever you want to do.
Most trans builders recommend not using the one in the radiator.

PontiacFan

iTrader: (104)

Why not? Wouldn't that just generate extra BTU removal? Bring the temp down thru 'what used to be normal', then use the added benefit of an auxilary cooler out in front to bring the temp down a bit further?

Makes more sense to me that way, ...

BTW, I know the auxilary coolers don't normally have an 'inlet' & 'outlet', but I stated it that way simply because of the mounting position that was noted.

9000th01ss

iTrader: (10)

like i said to the other guy, whatever you want to do.

extra btu removal? what if you generate 10,000 btu's and can remove 40,000 btu's?

i'm not seeing the need to get that scientific about a trans cooler.
i'm also done talking about this.

^^^^i have heard most recommend both, one reason is the radiator cooler is more efficient. so i run both and the tranny stays cool. i have heard success stories from both sides though.
