A340F Test Port location?

[HiluxSurf SSR-G]

Hi,
Does the A340F have a test port?


I've been reading about using the test port as location of the A/T oil temp probe being used by some FJC owners.


Thanks.

I've been looking all over the web. I also don't know and can't seem to find out if my a340f transmission has a test port?

Part # 35104A is what I found to be test port's. FSM shows gauge connected to lower front plug.
Same plug right rear, no mention of use, assuming it another test port.
Test procedure in FSM using front port, corresponding pressures.

The plugs have a J-spec taper, have yet to find J-spec specs for banjo fitting.
SST kit $600 - $1100.00

wile I use my torque ap for temps. I know there has to be an easier way as some people mount a permanent gauge, maybe they mount something in the lines to the cooler
related to that, the tundra and sequoia have a thermostat and hoses that route the tranny fluid to the cooler only when temps require....wonder if we can use those in a 4runner

good find on this!
I guess, a banjo test port can be fabricated to fit the thread

[MENTION=124615]3bears[/MENTION], The test guage is rated 300 psi, line pressure. Your referring to cooler lines, that's pump pressure is my understanding, different than line psi in that part of trans.

[MENTION=1707]HiluxSurf SSR-G[/MENTION], Toyota's SST kit has straight and bango fittings.
I haven't been chasing this hard, OTC might have something, a fluid gauge 300 psi not cheap, hose fittings.
You really gotta know, find a shop that won't jack you around have them do it for a Benjamin or 2 or 3.

If you are using the pump pressure test port then that will not be an accurate transmission temp. Fluid goes from the pan through the filter then to the pump. After exiting the pump it still has to go through every other part of the transmission before exiting to the cooler so temp at the pump will be much lower than the temp of the trans fluid heading to the cooler.
