Has anybody installed a Transmission Auxiliary Cooler on a Turbo Volvo? Where did it fit?

 

I put mine on the drivers side (US) at the bottom of the frame. I made a bracket that mounted to the frame then attached the cooler to the bracket. The air comes in through the airdam right onto it. It is barely hidden it hangs so low but it was the skinniest one I could find (B&M). I worry that one of these days I am going to come out of a parking lot and tag it. I picked up the fittings from HomeDepot and only had to get one extra trans cooler line to go from the cooler to the trans.

 

Thanks for the reply. Do you recall the measurements of the cooler? Have you installed an inline filter (e.g. Magnafine)?

 

Is there a transmission cooler inside the radiator? Just curious as to why you would put in an auxiliary trans cooler.

 

Good question. Yes, there is a transmission cooler integrated into / inside of the car's radiator.

Most people would not need an aux cooler. However, I plan to drive through some high mountains, close to max payload, in the summer; my car is already over 200k miles. It's cheap enough to add the aux cooler, I think it's appropriate for my circumstances.

I have installed aux coolers in many cars of mine and know about them a bit. If implemented correctly the aux cooler would reduce the transm oil temperature by 10-20 degrees, maybe more. At sustained heavy loads, this is very helpful.

These transm evidently are very durable, but they are not unbreakable. Just squeezing some more life from them.

 

Transmission Cooler Write Up

 

Thank you Gilber33

 

Reading the other threads about MBC / boosts, I would think that doubling the OEM boost would be another good reason to install the Transmission Aux cooler, besides using synthetic transmission fluid.

I think the Magnefine inline filter (about $ 20) would be a good companion to this upgrade.

 

Sorry for bringing back an old thread but I have a related question. Most of my searches seem to find that people have installed their auxiliary transmission cooler on the return side of the factory cooler. This leaves the auxiliary cooler the final cooler prior to the fluids return to the transmission. I was under the impression that the factory cooler was the final cooler that the fluid should be route to so that in winter the radiator actually warms up the fluid for proper transmission operation. Does anyone know the proper routing for sure?
I have found somewhere a factory external transmission cooler on 1999 C70. How is that routed?
Thank you for responding!

Respectfully,

BTW I am specifically speaking about a volvo 850. Fluid flow may be reversed for other vehicles.

 

Main Parts:

B&M Transmission Cooler 70265 $64.97 (Summit Racing)
Hayden Remote Filter Mount 2106 $25.97 (Summit Racing)
Wix Hydraulic Filter 51269 $9.97

Total without fittings $100.91

 

Drill holes to mount cooler to back of front bumper. The bumper is made of aluminum so it's not too bad.

 

Mount cooler. I don't have the fittings yet so ill post those pics later.

 

Remove battery and tray. Drill 3 holes for the filter mount. I have been using a right angle drill btw. I actually drilled the holes from underneath the car.

Mount remote filter housing below battery tray.

I'll finish the fittings tomorrow and post the pics of everything installed. I plan on splicing into the top cooler line. The proposed fluid flow is from the trans, to the remote filter housing, from the remote filter housing to the aux cooler, from the auxiliary cooler to the "in" hose for the factory transmission cooler ( top hose).
This is all assuming that the transmission fluid flow for my 95 850 goes from the top of the factory cooler to the bottom of the cooler back to the transmission. I'll know for sure tomorrow!
Any suggestions? Thanks!

 

Sorry to go slightly off topic, but, do the manual transmission 850s also have a transmission cooler integrated into the radiator?

 

Highly unlikely. Manual transmissions do not generate the heat that an automatic does. I have never seen one on a manual transmission.
