tranny cooler recommendations

[SJAndrew]

Stock, putting in TEP 4T65Ehd reman. What do you recommend?

Read around, you'll find some threads on the topic.

I have the cheapest one autozone had in stock on my car and the absolute hottest it's ever been is 200* on the hottest day with me beating on it a lot.

Well thanks for taking the time to post.

I recommend you tell us your objectives and limitations.

[SJAndrew]

Someone please tell me how to search these forums (aside from google). I knew how to on the old style, but I don't find a link with this setup.

My goals: keep the tranny fluid cool in an effort to promote long life (I don't care about performance, I prefer reliability)

Limitations: I am not made of money

Here is what I plan to get - it seems like it would be fine: More Information for HAYDEN 404 (Hayden 404)

The stock cooler should suffice.

[SJAndrew]

The stock cooler has 150k miles on it - TEP specifically recommended either a new radiator or a/m cooler (for use with my 'new' trans). It sounds to me like pretty much whatever will suffice.

I'm just going to see about finding a cheapie aftermarket unit (ala the Hayden I linked). I don't want to bother with a new radiator as mine works fine and I don't want to mess with bleeding etc (not to mention the A/M cooler is way cheaper).

Dave also sells the trans coolers and could tell you what size you need. I have one of Dave's installed, it is a 20,000 btu cooler. It is installed as a stand alone cooler, bypassing the stock radiator cooler. We just went through 100+ temps for the last two weeks, highest temp I saw was 179, through in-town driving.

Might want to inspect your rad first.

10 year old rads don't look pretty.

[SJAndrew]

My rad is fine - the AC condensor looks like crap though (ironic considering the A/C is the BEST AC I've ever had in any car, still frigid).

I know Dave will install them - he has a Hayden on his site. As much as I want to throw business his way, I can get a similar Hayden unit for 1/2 the price on RockAuto.

I don't have a temp sensor on my tranny (unless you guys are reading it thru OBD2 which I could I suppose). I have no idea how hot it was getting. My speculation was VERY VERY hot as touching the outside of the case was intolerably hot - just brushing it would hurt my fingers.

[matt5112]

Reading the OBD2 reading is the only way to go for trans temp.

IF you like to keep track of such things, it's a lot easier with an aeroforce scangauge.

[SJAndrew]

I had no idea - I have an OBD2 scanner, I can get coolant temp etc, I never paid attention to trans temp.

I currently havew the engine hoisted and axles pulled - the car is in my dad's barn (my wife would not take kindly to it taking u p the garage for a month or so). I will be over there this morning and see if I can get the trans temp pulled.

Thanks guys
