How hot does a 722.3 tranny case get?

Hi all
One of the eylets broke off my transmissin case. The exhaust bracket connects to those. I intend to glue it back on. The adhesive I have in mind is working up to 275 Fahrenheit. Is this high enough? Does anyone know how hot a transmission case can get? I know I could measure myself using a laser termometer. I do not own one though and maybe anyone of you knows the answer?
Many thanks, Bruno

Thanks for the suggestion. JB weld sounds good - it seems pretty strong and can tolerate up to 500° Fahrenheit. It is even easier to get than 5315HS from "extreme adhesives" that I had in mind.

If it works for this application I will be shocked. That said, I have been shocked before seeing what JB Weld held up to.

The fluid in the transmission normally reaches 180 to 200 F, which means the case will reach at least that temp. Add to that the exhaust heat and vibration and there's very little chance that this will hold.

I guess it's worth a try, but I wouldn't be too hopeful.

Good luck,

JB weld when applied correctly is quite amazing. I think it's weakness is it's lack of flexibility. Just be sure the surface is clean and not smooth. I have seen cracks in engine blocks 'fixed' w/ jb weld that held up for over 50K miles. Having said that, I can't get the darn thing to hold part of my mirror assembly together.
