Transmission cooler upgrade recommendation (5 Viewers)

[Gigem96]

I was able to get things looking pretty good with a little time, a screw driver and a can of coil cleaner. Lots of old crap came out. I’ll be testing it tomorrow and collect data with an OBDII reader.

Wait! How are you getting trans temp on OBDII??

 

[Gigem96]

Just a straight HF pick. Easier not holding phone! Lol

Does the OBDII read transmission temps? My transmission temp light goes on and stays on when I drive now even when cold. I am sure it's just a sensor but I don't think I saw temp readings available on the reader.

My scangauge2 doesn't measure tranny temp so I dont t think the ECU does either.

That's what I thought. I have seen some people add a bung or another way to put a sensor on there to check temps. In my case, I am sure it's just the sensor (they aren't cheap...about 80-90$) I will try taking mine off and cleaning the contacts and sensor.

I installed a sensor. I have never seen 190c with this kit that was installed going over mountain passed on 2nd gear and RPM 4500

what kit is this?

 

[Madcrix12]

I bought a Hayden trans cooler form O'Reilly's a couple years ago for $80ish that's worked great and plugged right in. Can't complain.

which model?

Hayden Rapid-Cool Transmission Oil Cooler - 687​

The 689 would work too

Cruisers and co should be able to point you in the right direction…

I ran a Derale unit, around 175F cruising temp and goes up to about 200F on 4 L

o, similar to factory unit

The tru cool 40k is the best trans cooler I’ve ever used. Not sure it will fit an 80

figured out my tranny overheating problem. radiator part clogged/failed so was blocking flow to cooler. bypassed rad and cooler finally was getting fluid to cool. gonna place a fan on the cooler, 7in should work right?

I'd have to go measure mine, but I think a 9" or a 10" would fit. Measure yours to be sure and keep in mind that fans generally measure an inch bigger in overall diameter than what they're advertised at. Another thing to keep in mind is that the area between the fan hub and the heat exchanger will see zero airflow and fans in the size range we're talking about all have roughly the same diameter motor. Go for the biggest that'll fit to maximize the area the blades push the air through.
