Is this too much not enough will it work. I will be using this as a stand alone unit and not going through the radiator cooler. Any recommendations.

Currentlt I have one of those el cheapo fin style trans coolers meant to be used with the radiator unit.

 

I say that you can't go tto big as far as tranny coolers go. But I would rather stick with one with A/N fittings so you can use braided line instead of rubber.

 

I would use my hardlines . I would cut the barbed end off then flair it and use a flair nut and avoid the rubber.

 

That would work as well.

 

Those work pretty good. The mounting ties don't.

 

I plan on mounting it on an angle on the core support with some sheet metal to guide air through it from under the bumper or I can just keep it simple and mount it on the core., but the shroud Idea sounds sooo cool lol.

 

Is there one available for stand alone applications that has its own thermostat? Preventing overheating is critical but it is also important to reach a proper minimum operating temperature. The factory setup raises the minimum temperature of the coolant surrounding the transmission cooler in the radiator and this helps raise the transmission fluid temperature.

 

I never heard of that. maybe others can chime in.

 

Hey copper look into a jag trans cooler I have one that was given to me I will take a pic if it for you it had quick dis connect lines looks solid to me and from my understanding was designed for th400 and 4l60e

 

im going th350 don't know if that matters. Quick disconnects sound expensive lol.

Lol buddy got this for me for free because of slight damage

 

that may be to small for my needs. I was thinking of using an old ac condenser but idk if there would be enough fluid flow. I got like 10 of em stacked up behind my box at work lol.

 

Tranny fluid doesn't work well when cold, which is why nearly every manufacturer runs it through the radiator.
I haven't seen much in the way of facts for sizing tranny coolers, but I bet that one is oversize unless you're planning to autocross.

 

I do drag race it a lot and have a loose converter.

 

1st things 1st. Put a temp gauge on the bottom of the pan. If the temps are ok with the stock unit, I wouldn't even mess with one. Just more places for leaks. I put on a Derale deep pan with cooling tubes, and never had a problem

 

True fact about the trans fluid temps. You want the fluid to reach its min op temp. Thats why on a street car I usually loop the the trans cooler in with the radiator so it maintains that min temp. Basically run the supply from trans into the after market cooler then to the rad then back to the trans. This method prevents dumping too much heat into the rad which would have a negative effect on engine temps. But on a race only application where a high stall converter lives a stand alone cooler is usually the better choice. You need to do some math...contact TCI, B&M, Hughes or any reputable vendor of converters & transmissions they can help you size a cooler for your application. They tend to size them by weight. Take a gander at Jegs or Summit. There is a whole slew of options right up to a self contained unit with its own fan. Do you have a temp gauge installed? That will help with sizing too. Need to see the temp flash when the car is "on the converter" especially if you have a brake.

edit J types quicker than I...

 

One of my reasons to going to a bigger unit is to avoid the one in the radiator to keep temps down. Crusing was fine but it crept up to 210 at idle with a 165 t stat. I'm going to a stock cooling system and doing the satnd alone unit as it is. I am adding a gauge I have one but I was told to mount it in the line with a jnction block ?

 

I'd buy a size or 2 larger. I used a full size air conditioning condenser on my 68 years ago and that transmission had close to 200,000 miles on it and still barked second gear when needed.

 

So the condenser idea works jag ? If so im in lol.

 

Yes it did I drove that car that way for about 120,000 miles.

 

Thanks

 

I believe the rule of thumb is to keep trans temps between 150-200. If you drive the car in winter, you may want to include the radiator cooler in the circuit as stated above.

 

No winter driving here. no heater which made for a fun drive to my parents house last fall when it was 32 degrees and I always drive with the window down lol.

 

All sounds good so far. The braided lines or comp fittings are much better than the rubber hose. Run a separate cooler for the trans,and let the radiator cool the engine.
If you don't have a deep pan,I suggest one.I have a Derale on a few,and finned aluminum on some others.Pleased with all if them.
A remote filter is not always the best idea,unless you use a great flowing filter.The typical oil filters are not designed to flow the volume of fluid that the trans is pumping through.If it restricts flow,it starves the transmission,and bad things happen. I did a test in this about 12 years ago,testing the flow of the lines,different coolers,and the remote style filters.Everything flowed well except for the remote filter.It was like hitting a wall.A Wix filter was pretty good,and much better than your typical Fram,Delco,or any other parts store filter.I just chose to remove the remote filter,and just have the regular filter in the trans itself.There are better filters for that too.I will get that info,as I keep stock of those.

 

I plan on using my steel lines no rubber should have some time to mess with it this weekend. Then weekend after next goes in my rebuilt th350.

 

I lived in Iowa where it's 30 below in the winter and no problems with the trans using the air condenser (fluid didn't go throw the radiator) that old 68 was my everyday transportation for years and never gave up.

 

I have been running a stand alone cooler about the size that you are looking at for about 3 years now with no problems. I also run the derale pan. I have had no problems when cold with the trans. An added advantage of the derale, is it has a drain plug.

 

Sorry to get off topic but where are you guys buying the finned trans pans I am looking for th400 but most that I have looked at say not bop

 

I have seen the finned trans pan in Jeg and Summit. In my opinion the best pan for a TH400 is the factory deep pan used on heavy duty trucks. They hold a couple extra quarts of fluid. Make sure you get the longer pick-up tube, bolt and spacer for the filter.

 

For now I got the stock pan Im not buying any pan until I know for sure my th350 will work . Then I will for sure buy a pan lol along with a custom converter.

 

That's strange as there shouldn't be any difference in the pan between a BOP trans and any other.

 

I was looking about a year ago and I swear I recall seeing not bop so figured something must be different but who knows maybe it was ebay can't remember to many parts bought this last year

 

Other than Olds never used a deep pan in any application that might explain why the seller didn't advertise fitting Olds.Pretty sure it was used only in truck and van chassis. There is no difference between a BOP case and Chevy case, other than bell housing. If the deep pan has enough ground clearance it will fit the chassis just fine.

 

Any Th400 pan will fit any Th400.

I got the Summit version,but plain because I don't like their logos on anything. It holds 2 extra quarts.

 

Thanks guys I just looked them up seems I must have got a weird one and never checked again tell now
