If I install this cooler what else would I need to do for the heat-xchanger delete?
Would I be able to run a MT radiator ? Anyone know what mods I would need to run the MT radiator ? My intent is to get rid of the coolant loop for the heat-xchanger when I go to a replacement transmission oil cooler solution.

Does it fit RHD Vehicles or not?

I would like to install this with a 160F thermostat. What thermostat should I purchase and what additional hardware is needed? And how would the thermostat be connected? Thanks.

Just as the directions state. You remove the OEM trans cooler and replace it with the upgrade. No more coolant in the loop.

Yes, it's at the bottom of the application list.

Improved racing is what I would go with. It would be a DIY or you'd have to take it to a professional.

First post!

Just had the BMS trans cooler installed on my 135i. I have an Improved Racing 160F tstat that was not installed with it.

So far even in a bit of traffic at 65F ambient the trans won’t go higher than 137F which is crazy impressive. But this leads me to believe that a stat is somewhat necessary to get it up to Temp.

Wondering what the best way to add the inline tstat is?

Can the BMS line be ordered separately?

Thanks for responding.

I understand the directions. I'm unclear on 'once the heat exchanger is bypassed' I would like to upgrade the radiator to a MT one [that does not have the coolant loop]. Just wondering if anyone is knowledgeable about any differences ie : Other coolant lines or any waterpump related issues that would have to be addressed once I switched to a more robust non-AT radiator.

FWIW I will likely be going with the kit for my e90 once I figure out if it's possible to transition to a MT radiator after that trans cooler is installed.

thanks in advance.

is it 10AN straight through from the trans quick connect fittings all the way to the cooler?

any upcoming sale on the kit ? (given it doesn't come with thermostat and not sure of the cooler quality)

No you shouldn't have any issues if you want to go to an MT radiator upgrade.

Yup! -10 AN all the way. No sales, we price everything very low to make it affordable for everyone. Piecing a trans cooler kit will eventually cost about $500-600.

I would get your own SS lines and get the quick connect an fittings, as well as buy a cooler for way cheaper. I built an oil cooler with a $250 thermo and still 50 percent less. The cooler is not amazing. Looking back I would not pay $400 for the kit. Bracket is convenient but I weld on up and it works fine.

Nice!

Can anyone in Arizona or somewhere hot let me know what their stock temps are in stop and go traffic?

I've had pretty good luck with this cooler but I noticed in 90 degree weather in stop and go my temps can still hit like 230 or so. I never logged my car in the summer with the old setup to see the difference

I was initially testing this in 110* last year during the hot summer.

In stop and go traffic my temps got up to 190* at most. After some driving it went back down to 160ish. I'd have to look over my logs... if I can still find them :(

How long is your drive? My drive home is 45 min to 1 hour now thanks to the mass exodus of Californians lol

You guys still have traffic over there? jk

Yes, my commute to work is 37 miles each way, so about 1 hour drive.
It's been really cool here, so maybe in a couple of weeks I'll get another log when the temps are 100+

You guys should offer this kit with a thermostat option. I think being plug and play having that option would be attractive for many folks.

Any chance on coming out with an N54 oil cooler plug and play kit as well?

Thermostat would bring cost up an additional $250, I might make it an option for those in colder weather. I haven't had any issues in our winter time when it gets 35* though. I'll look more into it though.

I don't think we'll be coming out with an oil cooler. Too many options already out, hard to compete with ebay at $100 for a PNP kit lol.

I live in Wisconsin, so the thermostat option would be awesome.

T-stat doesn't cost $250 but it is surely you who decide the price of the complete kit...

It depends on the thermostat of course, plus it's not just the Tstat, it's the two extra lines and fittings as well :)

We'd use either Improved racing or Mocal thermostats.

I would like to retain the original cooler/heater and put a thermostat and the bms cooler kit in between the return line. Would like do fit this myself but i can't find the right adapter fittings. Anyone know where to find these?

The stock one has a thermostat built in.

Thanks!

Stock heat exchanger cools oil just after it reaches 200 degs by opening the passage in the water leg - T-stat is controlling the water, there is no T-stat in the oil line...
Otherwise the oil would not circulate if there would be closed valve in line (T-stat)... think about the engine oil cooler/T-stat, it is the same thing...
A proper solution is to dump the whole heat exchanger, run a cooler w T-stat (170-200max) + a vent to keep the temps happy in the city/low speeds

I was under the impression that it was heating the trans oil until that's up to operating temps. Now I know better so thanks for the explanation!

What is this "Vent" for our cars?
