transmission cooler install
Sorry to ask this question that seems to be answered so many times with different variances in many different threads as I still don't understand.I have read them all. I want to install my transmission cooler in line with my existing cooler, This is the cooler I have purchased.
Do I only have to cut the top line ? The top line that comes from the radiator then goes into the cooler and when it comes out of the cooler it goes into the other half of the line that was cut? Is this correct? Anyone have any picture (not the schematic) of the lines running actually using both the radiator as well as a external cooler installed? Its just confusing and I know it shouldn't be but that's why I am only asking about running them both as that's the way I plan to do this. Any help or pictures is appreciated. Thank you

i didnt cut any lines when i installed my coolers i simply disconnected the tranny return from the radiator and installed a fitting and then just slipped a rubber hose over the tranny return line and the other end over the new fitting use hose clamps of course then just cut ur rubber hose where u want ur cooler to go and ur done.

Thank you. So this goes in the top of the radiator, hose from this goes to top line of cooler. Bottom line of cooler goes to hose removed from top of radiator. Correct? How much fluid is lost in this exchange and what were the temp results on your vehicle?

I have a pretty large RV cooler hooked to mine. Running through the radiator and see about 180 max. As long as you go through the radiator you will see higher temps because it will actually be heating it up. I plan to bypass it and expect temps to drop quite a bit.

yep it really helps out alot i use to see 200-210ish before i did my cooler install now like i said before it usually stays at 140ish but keep in mind if u are ever parked somewhere and leave the car running for a while the tranny temps will get up in the 180s or higher depending on were u live the 140-150 im stating im getting is with the vehicle in motion and air passing through it.

This is a large cooler I ordered. It was 32 degrees here 2 days ago and I was at 208 in traffic that was slow moving. If i can get that down to 180 I'm good with that, if it doesn't work out that well I will try it stand alone and see if that's better. Thanks for the input.

Oh I know it helps out a lot. I was seeing 212 temps. Just would like it a bit lower even so I'll pry bypass this, spring.

youre not going to increase with the cooling capacity with the stock cooler inline, in standalone config you can optimize the one pass of the trans fluid without the heat soak from 192-200 degree coolant.
In AZ where i live (up to 120 ambient i manage to stay under 187 year round using a junkyard oil cooler as my trans cooler and external filter..this year though with the addition of the stall i will utilizing a longer oil cooler that will mount directly to the ac condenser to help out.

I installed the cooler inline, install would have went easier if I didn't spend most of my time trying to remover the lower cover to install from the bottom. I never could get the piece out, even if I had been able to no F'in way I could have gotten it back in. Removed all the grills and the latch assembly, put it in thru the top. I used a Hayden Rapid Cool 679(30000lb) and a Hayden adapter part number 397. I didn't cut any lines. Bought some fuel injection clamps also for the ones that are harder to get to and doubled them up. Also installed an inline magnetic filter from Raybestos. Didn't mount it the way I was hoping to but it seems to get good flow and it seems solid. Not overly hard, but not a real fun job either. Took it out on the highway for a 25 minute cruise and the temp didn't get over 129 degrees. The real test will be my work commute and sitting in traffic I will have to monitor and see if it helped as I was hoping for. I will post back once I get some real results.

Just posting back some results after 2 weeks of commuting. Temps here last week were high 60's low 70's, this week its been cooler. In my 45 minute commute I saw a high of 172, and it's usually around 164 since the install. Still early to tell , once the temps get hotter will be a better test although right now I can defiantly tell it has helped . I really wished I had payed very close attention to the temps from day one, but I really only started monitoring this since noticing the transmission problems and reading all the transmission posts. Very good idea for anyone who has not installed one yet, money well spent.

or
is it going from the top rad fitting out to the cooler then the filter is installed on the return side of the external cooler to the trans return line (line from the original top rad to trans)

I unhooked the top radiator line and installed the fitting into the radiator so nothing was cut. The line from the radiator with the fitting goes into the cooler(in). The line that exits the cooler goes into the external filter then attaches back to the original line removed from the top portion of the radiator. I live in a cold weather area so I think this works best for my car, yours could maybe benefit from stand alone depending on your area and that is a decision you need to make. Hope this helps.

i have a question about the transmission line fittings in the radiator. do these just pull out? or is there a tab to pull or squeeze to release the line?
and am i correct on splicing a add-on cooler into the top transmission line on the factory cooler/rad?
