Transmission Fluid Flow Rate

[IZwack]

I may undertake a personal project this winter dealing with our transmissions during off road use.

Anyways, I need to get an idea of the rate at which the transmissoin is pumping fluid -- for example, at the lines that goes from the transmission to the transmission cooler.

So does anyone have a figure say during idle or at a certain RPM (gpm or lpm) ?

Since the lines are thin, the GPM rate can't be too high. The thinner the line, the higher the pressure, but the lower the GPM rate. Northern Tools sells digital flow rate meters.

Thanks Dogfriend. Your answer was here in post # 13: http://www.explorerforum.com/forums/showpost.php?p=479441&postcount=13

sorry to jack the thread, but how much tranny fluid should my 98 v8 explorer have?

I don't know if I'm on the right track here,
A friend with a 70 1/2 camaro ( I know) , had a power steering pump leak. Did some research and discoveres that some guys are running the ATF lines to the steering box, then cooler, and eliminating a power steering pump.

Isn't this harmful to the front pump?

sorry if this is hijacking?

Maybe, but its just a Chevy, so there is no great loss.

Actually, I would wonder if the steering force might be kinda erratic with that setup. I don't know how constant the pressure is in the trans cooler lines.

In my factory manual, there is a transmission cooler flow test. To perform the test, you disconnect the cooler return line from the transmission and reroute it to fill a funnel in the fluid filler (dipstick) tube. According to this test, you should get a flow rate of 1 liter (1.05 qt) every 30 seconds.

There we have it - thanks! I'll assume this is at idle Thanks again!!

I guess that would work for emergency purposes but I don't think the transmission's pump provides enough pressure to fully support the requirements of the steering box.

Yeah, we sometimes do a flow check before we install a new transmission. We test out of the cooler to make sure it isn't stopped up

Sonnax corp actually makes a flow tester called Sonnaflow, to check out adequacy of flow. Not sure if their test data is readuly available anywhere though.

Glacier,
I tried emailing, send you private messages. and calling you?
