Will GM 200r4 work with factory floor shift location?

Well I discovered something interesting while I was looking for a nice looking trans temp gage (at least one that would go with the cuda dash). Anyway, some gages only go to 250 degrees and some go up to 400 degrees. I know it's not good for tranny fluid to go above 275 or so from that chart I posted earlier. I'm running synthetic fluid so just out of curiosity I starting searching to see if synthetic can withstand more heat than regular trans fluid. Ran across this site where they were talking about different temperatures depending on where you mount the sender. Turns out if you mount it on the trans pan (drain plug) max in the sump is 285 degrees by GM standards (2004R, 700R4, etc). Now remember, this is for regular trans fluid (synthetic would be higher). But if you mount it at the pump output, in this case the upper fitting on the 2004R, then the max reading can be 350 degrees because the fluid from the pump is at it's hottest point.
All this makes a big difference!!!! If you mount it at the pump outlet then you'll need to buy a much more expensive gage because the ones that go to 360- 400 degrees are $100-$150 more. I don't care if the gage only costs $49 if it's a good brand and as long as it measures the range I need and there's no point in getting a super expensive gage if you can mount the sender in the pan. To make it even more interesting, if you do buy the more expensive gage to mount the sender to the output line you still have to spend another $30 on a manifold to tap into your trans line where the fluid leaves the pump.

So I'll just buy the 250 degree auto meter for $54 and mount my sender in the pan where I had installed a 1/8" drain pipe plug. Easy peasey, lemon squeezy!!

Hope your ready all this JBC426..........
