In my recent quest for achieving cooler transmission operation, I recently acquired an XC90 trans cooler, a couple spare cooling line hoses should I need them, and I bought a brand new Nissens radiator from on FCP. I bought the radiator as I'm fairly certain that mine may be passing fluids back and forth, and if I completely eliminate the stock trans "cooler" (which isn't actually a cooler, but an aid in warming up the trans quicker) I fear that it'll begin to leak without being properly sealed up. Plus it's not a bad time for some preventative maintenance putting in a new one and maybe lowering operating temps overall. My question is what's the best way to do this job and remove as little as possible? I namely don't want to nor have the equipment to properly remove the A/C condenser. I know that the job requires dropping the radiator from the bottom, but I've heard you can actually leave both the condenser AND intercooler in place... If that's the case, I'm all for that though I'll bet having the stock I/C removed as well would be helpful. What says those that have replaced their radiator before? There's almost nothing on the YouTube, and I only found a couple threads though Google from I think Volvo Forums which is where I read that you can actually remove only the radiator leaving the other 2 items in place... I also have fresh Volvo coolant and a case (12qts) of Mobil 3309 on hand as well. I plan to run 16oz of Hot Shot TSE/Trans Stiction Eliminator mixed in with the 3309 fluid which should clean things up hopefully. As before I plan to capture a sample of the current fluid to send off to Blackstone like I did at the last Gibbons method fluid change that I did on my trans.
