Anybody have pics or info on a rear auto trans cooler install in a C-4. Can't install in front,, Thanks

 

I'm curious, why can't you put one in the front?

 

Installing in the rear doesn’t give you a great shot of good airflow. Look into something that has a fan mounted from Setrab or Derale.

You can remove the spare tire snd use the tub as a mount or just replace the tub with a sheet of aluminum or stainless and mount the cooler there. I had a cooler for the ZF there and worked pretty good.

 

O-yes fan, spare gone, looking at a Derale with fan, been reading about people that mounted the ones in the front C-4 Corvette the temp went up (talking about the big one with big *** fan), spent lot's money time to keep the temps down in this southern clement with the A/C on not going there . Thanks ..

 

Thanks ,

 

I'll throw this out there. Ultimately it's your ride and you can do whatever you see fit. But there are a lot of us who have large front trans coolers that have low fluid temps. My 84 has a 4L80e with an internal temp sensor. On a 90 deg day while beating the snot out of the car the highest temp my data logger ever recorded was 180 deg F. Typically cruising down the highway it's around 170 ish. My bone stock Silverado with a 4L60e hits 200 Deg F all the time. I use a 1 inch thick plate style cooler only. I'm using a Griffin Racing radiator with no built in trans cooling. The only cooling my trans has is the plate cooler in front of the radiator. I welded together some mounts to attach the cooler to the frame of the car instead of mounting it to the radiator. Good synthetic fluid reduced my temps some also but I've never had trans over heating issues with this setup. Also a good converter can lower trans temps. I have an FTI 9.5" billet converter. FTI claims that there billet converters will lower temps. Not sure if that's true in application or not but in my case it seems to be holding water.

Not trying to argue or anything like that. Just saying that people have used front mounted coolers with success. If you would like pictures of my setup I can post them if you like.

Thanks for taking time to give your thoughts on this trans cooler deal, this is a restored 93 LT-1 I do all the work myself installed new trans, it was dismantled and painted new rubber sports seats carpet and on and on one more on about burnt out on working on it then Bam trans goes then the new all alum. 3 core radiator trans cooler fittings started leaking so going after market cooler, I want this to be a one-time deal installing one anywhere no easy task so trying to figure the best place to put it, thinking big *** cooler with fan in the back a lot easier than removing the radiator and making bracket and hoping the motor temp does not start going up , spire tire gone 30 years old it was crap anyway ,thinking ,THANKS

 

[QUOTE=radar502;1607381548]I hear you. I hate doing things twice, also that sucks that the trans died. No matter what you decide to do with the cooler if you use a large cooler only and stop the trans fluid from going through the radiator your coolant temp will go down. I did my radiator and the trans cooler at the same time. Now to be fair I replaced the factory radiator with a much larger one with no built in trans cooling. So my drop in temp had more to do with that. But still removing that hot oil from the radiator and using a radiator that doesn't have to devote room for trans fluid has to help lower coolant temp.

Last week I re-did my trans cooler mounts. I've had the cooler that I have now ever since I put in the new radiator. But back when I did it I used those glorified plastic zip ties that pass through the radiator to hold the cooler directly to it. There were rubber pads between the two. Then I used braided steel AN hoses to connect it. Well this winter I decided I wanted a better mount. I just removed the upper radiator shroud and was able to fab brackets that bolt to the two bolts on each side of the radiator that hold the cooler. It sits in basically the same location it was before but isn't attached to the radiator at all now. This was fairly easy to line up being that my trans cooler is almost the same width as the radiator.

If you decide to go with a rear mounted cooler and fan I would absolutely use some PTFE braided steel or braided nylon hoses with AN fittings. Getting those lines back there are going to be a bit of a pain and the flexibility of that kind of hose will help a lot. Also the PTFE stuff has a smaller O.D. with the same I.D. of the traditional rubber core lines. So it would be easier to make fit around the differential. I know this because I used the same stuff to make my new fuel lines. Routing anything hose wise in the back end of these cars kinda sucks.

 

[QUOTE=Phobos84;1607381937]Three core Alum. radiator after about a year the stainless lines in the alum (not good). radiator started leaking so removed the org. lines, I installed a cooler in front of the power starring cooler also I installed a MaxTow heat gauge ,this set up is ok for now but can tell this summer not going to be big enough so installing a stacked plate cooler with fan in the spot where in the back were old tire used to be , install a on off Toggle by my temp gauge got some new 72 in stainless lines they might work might not ,I would like this to be do it once forget it deal so plaining it out best i can ,got temp gauge so I can keep up with it , not just guessing ,way too much money and work to do this trans by myself again NO NO ,been there done that not fun .. Get all the parts together this spring dive in .. Had my trans rebuilt with HD parts upped the pump pressures ECT, this thing is a head snapper goes into OD at 58mph on in and out of OD in traffic I like it , With my labor and rebuild $4500.00 -$5000.00 worth I'll put coolers on ever conner if have to LOL Thanks .
