I have a 1994 f-150 xlt 4x4 with an i6 and 5 speed manual transmission. I'm looking for the transmission test port. Does it even have one? If so, where is it? Thanks

 

I do not think it has one. I think only the automatics had them.

 

Do you know if there's any other way to hook up a transmission temp gauge? Thanks

 

A trans temp gauge is pretty much useless in a manual as heat is not an issue.

 

I guess I don't know what you mean by a "test port."

On my '88 M5OD (F-150, 4.9) there was an "observation window," down low, I believe on the driver's side of the bell housing, that is easily accessed by grabbing the rubber plug (approx. 2" square, IIRC), with with your fingers or a screwdriver, and pulling it out.

I can tell you for a FACT that you can observe the motion of the concentric slave cylinder, (encircling the tranny's input shaft--definitely NOT one of Ford's "Better Ideas!", as it requires dropping the trans for a simple maintenance procedure, i.e., replacing a bad slave cylinder--on the F-250's ZF trans, the slave cylinder is EXTERNAL to the bell housing--/rant over) through this observation window.

Is that what you're asking, or am I off-base?

Well, I wanted to install a transmission temp gauge. And to attach the wire to the transmission, there's a stud that I would screw into the "transmission test port". That's just what the videos I've seen the installation are calling it.

 

The only way it'll work is if you buy an actual thermocouple to screw into the drain plug on the trans and wire your temp gauge to the thermocouple.

 

I understand how the gauges hook up. In fact I have one coming in the mail today. However, they are intended for an automatic that is subject to high heat.

 

Yeah, I get what you're saying. That makes sense. I was just curious. Thanks for your input!
