fordy_alexsupra Posted June 18, 2012 Share Posted June 18, 2012 Replacing my radiator soon (with SRD rad) which removes the stock tranny cooler. Purchasing a tranny cooler is required, What is the safe way of assuring a proper tranny oil warm up or will the oil warm-up eventually to safe temperature if left at engine idle a couple of minutes? Not forgetting cold snow winter conditions, even though I avoid fun 180s amap haha. Thanks for comments . Quote Link to comment Share on other sites More sharing options...

Mocal do a thermostat that you can put inline and it will re-circulate your gearbox fluid until it reaches 80c and then open and send it to your new cooler. I asked SRD about their rad sometime ago and Lee suggested that it was ok to use a cooler on its own but warned the changes may be a bit rough until it warmed up. But like you I am worried that during the colder months it may never get up to temperature with a cooler and no stat. Here you are, but note that the pipes on the supra are 3/8 not 1/2: http://www.ebay.co.uk/itm/MOCAL-OT-1-REMOTE-OIL-COOLER-THERMOSTAT-SAXO-205-GOLF-GTI-CALIBRA-TURBO-MLR-SQ-/150837151519?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item231e98471f#ht_1435wt_821 Edited June 18, 2012 by Shane added link (see edit history) Quote Link to comment Share on other sites More sharing options...
fordy_alexsupra Posted June 18, 2012 Author Share Posted June 18, 2012 Thanks for reply interesting to know there is thermostat, maybe im just over concerned bit to much for what its worth because x4 adapter fittings are required then. Ill just have to think about this haha feel a little undecided on what to do now, whether to put in the extra work and money or do the easy way! But must be a reason for autos to use pre-warmup Quote Link to comment Share on other sites More sharing options...
fordy_alexsupra Posted June 19, 2012 Author Share Posted June 19, 2012 I researched that the B&M coolers with there flat, stacked and small passage way design, bypasses and slows the 'thinker/cooler' oil so it warms up to temp faster.

garethr Posted June 19, 2012 Share Posted June 19, 2012 Mocal thermostats are also available for 3/8" hose http://www.thinkauto.com/acatalog/On_line_shop_Oilstats_30.html Quote Link to comment Share on other sites More sharing options...
tDR Posted June 19, 2012 Share Posted June 19, 2012 I ran 3x trans Coolers with my BL trans, plumbed in series with no stat - never had a problem then but did break a BL trans when running only 1x trans Cooler. I was also running a PI 3,800 stall TC. My car is still going strong thousands of miles on with that setup, now owned by DekJZA80. Cheers, Brian.

fordy_alexsupra Posted June 19, 2012 Author Share Posted June 19, 2012 Top man makes things easier. So if the oil drops below 80c while driving the thermostat will close/ restrict tho flow of oil? Ideally it will never go blow 80c? I may get two coolers for peace of mind and future projects Mocal thermostats are also available for 3/8" hose http://www.thinkauto.com/acatalog/On_line_shop_Oilstats_30.html Quote Link to comment Share on other sites More sharing options...

Interesting, do you use it all year round and if so do you notice any difference when it is cold? Do you have a gauge to keep your eye on the temp? I was chatting to a guy the other day who has just singled his 1jz and noticed that he didnt have a stat in line with his large external cooler, he reckoned that on the Soarer they didnt pass the transmission coolant through the rad for warm up first like they do on the Supra, yet its the same gearbox. So maybe a stat is not required. I guess the car like all cars is designed for sale in lots of countries and some are going to be a lot colder than it gets here in the UK.

fordy_alexsupra Posted June 19, 2012 Author Share Posted June 19, 2012 I don't think I will bother with Mocal OT 3/8 on very cold weather I will just idle a few minutes and get a large 11x8x1,1/2 b&m cooler. Time to measure up behind my stock bumper, hope something that size fits in the space in front on the front wheel haha?? I'm only BPU atm Quote Link to comment Share on other sites More sharing options...

Hi Shane, I've not owned the car for a couple of years now but I ran it with no trans temp gauge (ignorance is best when you're chasing times! ) for a couple of years including a snowy winter and can't say I noticed a difference - it always shifted firm but was tolerable, I had no stock TC butterfly either so didn't get any shift retard. I'm also still in touch with the new owner who asks me about stuff / for advice now and again and he's never mentioned the shifting either and that's through two harsh snowy winters with him. Cheers, Brian. Quote Link to comment Share on other sites More sharing options...

fordy_alexsupra Posted June 19, 2012 Author Share Posted June 19, 2012 Brief change in subject to my topic but as this cropped up, What is the benefit in removing the traction control (TC) over just turning it off using the switch? Quote Link to comment Share on other sites More sharing options...
tDR Posted June 20, 2012 Share Posted June 20, 2012 The short answer - the stock TC system still does 'stuff' even though you've turned it off with the switch, like throttle retardation on autobox shift using it's own butterfly inside the throttle body - hence the stepper motor you can see bolted to the side of the throttle body just ahead of the intake plenum as well as a whole separate TC ECU located beside the main ECU in the passenger footwell which works in unison with it. You will find that you won't be able to get a dyno power reading for your car if you ditch the TC ECU as your car will always want to kick down and jump out the dyno during a power run. I could never get a power reading from mine and when at the dyno with ryang, this was the reason he gave for it. As a side note, I ran Amsoil 'Fully Synthetic' TypeIV ATF rather than the Toyota stuff. Quote Link to comment Share on other sites More sharing options...

Iv brought some toyota ATF T-IV 5l from toyota for £50, now Quote Link to comment Share on other sites More sharing options...
tDR Posted June 20, 2012 Share Posted June 20, 2012 Just pull the TRAC fuse to see the difference (fuse box under bonnet). You will get a warning light on the dash to ignore this way though. Quote Link to comment Share on other sites More sharing options...
fordy_alexsupra Posted June 20, 2012 Author Share Posted June 20, 2012 After removing the fuse, Would this not put more strain on the gearbox if the airflow/engine is not restricted? Decreasing the life, just a concern really? Should start a new thread on this really lol Quote Link to comment Share on other sites More sharing options...
tDR Posted June 20, 2012 Share Posted June 20, 2012 Yeah, start a new thread as a number of us have gone TRAC-less in the past so you'd get more input. On paper, you're harder on the autobox yeah - the main issue is heat so depends how much you do it, how much torque you're producing and whether you have cooler(s) to help. Personally, I dragged a stock TT auto all day at Crail with the TRAC fuse pulled - about 20 runs in all - and had no issues with the car after. Refreshing the ATF helps, if you know you're giving it more than standard abuse then service it well and with decent fluids etc. Quote Link to comment Share on other sites More sharing options...

fordy_alexsupra Posted June 21, 2012 Author Share Posted June 21, 2012 Thanks as iv gone bpu I write down my mileage and schedule regular services! I will try the non traction method The oil warm-up was covered and the beginning of the thread Quote Link to comment Share on other sites More sharing options...
