my car has a 3200PI stall in it right now. I installed the big boy race B&M cooler with all the russle fittings and all the good stuff. Current trans temp cruising on the highway is about 160-165 degrees. Around town it doesnt get past 175 degree. Whats your trans temp running?

Those are very reasonable good temperatures

Mine stays about--212-220 (no cooler)

110-125 winter, 150-180 highway summer, i take it easy when it gets over 190 after romping. b&m 24000 mounted dope style

Gilbert@Ace Racing

I would not be afraid of temps in the 200 - 215 range. As a rule though you want the trans temp to be somewhere down in the 170 - 190 range.

If it stays above 200 much I would recommend changing the fluid more often. Just a thought.

how do you check trans temp?

Gilbert@Ace Racing

You'll need to use a Trans. Temp. gauge. It has a sending unit that is similar to a manual engine coolant temp gauge.

With my loose yank pt4000 that does not lock in mid 90 degree temps city driving is about 150-160 with 2 trans coolers. On the highway im seeing just about 180 for 30 mile non stop drives on the highway at 85~mph at ~3100rpm...my sending unit is in the pressure port I hear the temps are about 5-10 degrees off from when in the pan..so even if it was hotter its not to bad

Gilbert@Ace Racing

Yep, those temps sound perfectly normal.

My 4l80e is around 185 when driving normal. It has gone to 215-220 when driven hard. Should I be concerned?

No you have nothing to be concerned about thats still well within a normal range

in my #4500 truck with SS3600 and FLT trans, I have never seen over 150* cruise temps and 190* traffic temps. I have -6AN cooler hoses and a 34K cooler mounted up front in some good air.

In 85 deg.temps I see about 160 trans temp. Mine is mounted in front dope style. it has a fan,but it only kick in at 180 deg temps. Its a perma cool with a fan.

Say you were doing some serious roll racing on the highway several times to insane speeds and the trans hit 240-250 how long would the temps have to be up there non stop to do some damage?

Wes Brannon

I have this alot also!!

Gilbert@Ace Racing

That is relative to the condition of the internal soft parts and fluid.

Here's how it goes typically... the fluid breaks down, clutches, steels and seals become glazed and clutches begin to slip under load and when applying. This slippage builds heat, the heat damages parts like the rubber seals on the pistons that apply the clutches, the slippage gets worse, the clutches get worse... then it fails. It is a condition that can happen slowly over time or can happen instantaneously if a seal fails under pressure when it is under load at high temps.

If you are running your car under those conditions I would highly recommend frequent fluid and filter changes! The fluid breaking down is your enemy. Further... get an aftermarket cooler on that thing, if it does not help get a dedicated fan on the cooler!

Good Luck.

SS4000, 160 most of the time, beating on it or stop and go 180. Only one time it got over 190 and I pulled over and let it cool. I have the 29000 b&m truck cooler.

i have learned that the more you race and the harder you drive the more ofen you need to change the fluid, this will also he3lp lenghten the life of your trans.

so dont go cheap when it comes to your trans and accessories
