I know most ppl are either putting the sender in the hot line or using the second test port. I installed my guages yesterday, and when I tried to thread the sender into the second test port, it wouldn`t thread in. The hole there on the tranny port is too small for the probe on the sender to slide into. The threads are correct, but the sender won`t slide into the hole far enough for the threads to catch. I pulled the plug out of the front test port and the sender went into it fine. My question is this, do I need a differant sender, or will the front port work ? The gauge works great there from what I can tell, but I`ve never heard of anyone having this problem and had to use the front port. Will it work and be ok ???

TIA

 

i think i put mine in the front as well...cant really remember it has been awhile ago and i have no idea where the install directions went to hopefully someone else will chime in as my truck is outside and it is dark

 

I put mine and 35xj's in the rear test port on our 48RE's. Ours are Autometer Phantom series gauges FWIW.

I have verified our temps with my DRBIII and the temps are within 5* of one another.

 

does the rear test port monitor fluid in all gears?

 

Wow, no one else has had to put the sender in the front port ????

 

so do you guys get a better reading from the prots on the tranny than in the pan. I know they would be a little more gradual in the pan but still show the overall temp of the tranny. Should I move my sensor to the port and plug the hole in the pan or what??

Also not to sound like a moron but where are these ports on the tranny? Obviously I need to remove a plug from the tranny but where???
Thanks for the lesson in advance!

 

On the 48re's there are 2 ports on the passanger side of the tranny.

043500QC- I'm in the same boat as you. My directions specifically said to install my sender in the second port(the one furthest back) and it semmed like it would thread in but it wouldn't go when I tried tightning it down. I never tried the front port cause it didn't mention that at all.

I beleive one of the bell reducers in the kit is suposed to go on the sender first then they screw into the port as one? Well all 3 of the bell reducers that I received are way to big for the ports, so does that mean that just the sender goes into the port alone?

 

Do a search for the ports, you will get a lot of pictures of all these ports. I've had them in the front one, and it's not a good spot, spring and solinoid in there, and if you break the tip of your sensor off, yeah no good.

Most put there's in the pan, or the hot line comming out of the transmission. Sure it involves dropping the pan, or cutting the line but you need to figure out what you want. I wanted to moniter the hot line, because you need to know what the fluid had gotten too. If it gets to hot you need to change it. If you moniter the pan, your getting fluid after it's cooled. So you may say wow it's getting pretty hot, but in reality it's already gone over a temp that you should have changed it at. It's all what you want. I wanna know what the temp is comming out, so if it gets hot, I change it. you may never see this in the pan.

there's a picture in my gallery of where I located the temp port. Bedrammerjammer did a similar set up (if not exact) His pictures even show two different types of fittings, one flair, one compression.

As always you can PM for a more precise answer

 

I took the really easy route and ordered the Dipstick probe from genos. You just pull the dipstick out and slide the probe down the tube until it hits the bottom and then put the dipstick back in. Works just as well as putting it in the pan. Yes I know the temps will be lower than the hot line but I'm smart enough to add a few degrees to the guage reading.......

 

I just installed guages in my truck. I chose to go with the port in the transmission. I read on another site to use the port that is at the rear of the transmission and the port faces the passenger door. It seem to work fine.

 

I think you're pullin our leg. Does such a thing really exist. Guess I have to go to Geno's and find out.

 

It really does exist at least for my Westach guage....

 

If the pressure test ports are used to read temperature, you won't get a quality reading.
The fluid needs to be flowing. Those ports are more likely to read CASE temp than anything else.
Best place will be in the cooler lines, next is the pan.

 

I'll be darn. It does exist. I thought for sure you were trying to pull one over on us. My appologies sir.

 

I would never llie to my DTR friends. How else could I have built an 800hp/1500tq monster?
