Aftermarket trans. temp sender on a 4T60E

[Azrael]

I have an autometer trans. temp gauge and the sensor it comes with is 1/8" NPT and comes with 2 adapters (3/8" and 1/2"). Is there a good spot for one already on a 4t60e or will I need to get a T-fitting to tap into a fluid line? And if I need a T, which size would I need to go for? Thanks.

An update: Tried to get a transmission shop to install it during a fluid/filter change and they couldn't see anything to screw the sender into and that brazing one of the adapters as a bung (as suggested in the instructions) was out of the question.

You should be able to tee it off of the trans cooler outlet line.

you can get an external transmission filter kit from perma-cool. you get the remote filter mount, lines, and clamps. i believe it has a provision for a temp sender. not to mention the added filtration, it uses a spin on oil filter PH8 fram or equivalent, it catches what your stock internal filter doesnt. you get a place to mount your sender, and better protection fot your tranny.

you can "T" into the cooler line fitting. the proper way to do it is to braze a bung into the pan and put it in there

I just found out there's a spot on the 4T4xE's that's perfect for a sender. Hopefully it'll be similar on the 4T60E. If not I'll just use the excuse to get a transmission fluid cooler. It should be very straightfoward from there.

The best way to do it is to remove the pan and braise (braze?) in a bung.
That way you can also use it as a drain plug in the future.
Just a thought. Worked for me.

I suggested brazing one of the brass adapters the gauge came with (as the instructions suggest) but the shop I went to refused to do it due to the dissimilar metals. I ended up finding a T-fitting/manifold from autometer that'll do the trick (overpriced and overengineered no less)...just need to find the time to splice it into the fluid line to the radiator.

Everyone seems to have a differing opinion on this. Here is mine. I used a tee in the return line so as to monitor the cooled line temp return to the trans without the case heat gain. That way you know if the return is really getting hot you need to back off and get a bigger cooler or add another one. just use a 1/4 tee and some barbed fittings. Probably cost less than $5.00 at any parts house.

WTF that is what brazing is for. To join dissimilar metals. You also could have silver soldered it that is the strongest way to do it.
