I have the '95 Dodge line with the temp port built in. The area around the port is very hefty and I don't see how that could be a weak point. If you use the T type adaptors, I can see that being a weak point and possibly breaking. I would also like to know how many degrees the stock coolers bring down the temps at each pass. Trying to compare pan and line temps is like the difference between pre and post turbo EGTs... they are just not the same and some guys have found the difference between the two is far more than the 300* often mentioned. IMO the only place to put a trans temp sender is in the hot line.
