alright i have a decent picture of a transmission, im trying to find the exact place to put the temp. sending unit in the drivers side of the transmission. the only thing is that my trans has some black box cable system kinda thing on the side of it and it makes getting to the only hex plug i can see kinda difficult... does anyone have or can anyone take a picture of their transmission and point out where the sender would be screwed in? preferrably with the electric box on the side of the trans instead of the picture bear?

the green circle is where the elec. box/ cable wil be found and thunder550 circled in red where the port should be but does anyone have a pic with the box on it? i cant tell if the hex thing i see is that port to the left inside the green circle or if i see the one circled in red.

sorry for the rediculous post but i dont want anymore problems.

also, what should i use to seal the threads, not teflon tape, but what?

Dude seriously buy an escalade cluster my trans temp gauge on it was within 5*s according the HPT. Plus the cluster looks better you can get em off ebay for 240shipped almost as cheap as a nice autometer unit.

The port that you trying to use I don't recommend. I would put it in a bung in the oil pan or in the return cooler line. There are kits out there for this and this method will give you a true reading. The main line pressure port is not a good place to mount the sender IMO.

Check out my pictures here

I agree with Vince - the pan is the better location for sender unit - mine is currently in the pan. But, I will tell you this: under my own observations and testing, I get the same temp readings from the pressure port as I do from my pan.

If you choose to use the pressure port, it is circled correctly (in red) in your picture. It is the only thing there, there is no mistaking it.

You need nothing to seal the threads, just tighten it up.

i dont really want to fool with the cluster, i used to have the temp port in a remote filter with auxillary port but the filter would impede the flow way too much and the line entering the filter, the other dy swelled and split so that made for a whole lot of smoke and a good scare so i bypassed that and now im looking for the easiest place to put the sending unit. sounds like the circled red place is it. vince, i value your opinion, why do you not like that location? not accurate? does anyone know what size the hex is on that port? is it 12mm? thanks for the input everyone, oh, vince, do you knwo where i could get a kit that you are talkin about if it really is not that good to put it in the main prressure port, if its non sponsor just PM me or something. thanks

mine is in the port and has been there for 6k miles and also had it in the port on my stangs tranny also and didnt have issues

I don't feel that you get a correct reading. I believe this to be true due to the fact that when I run a trans on a dyno I use that port to test line pressure. We also hook lines up to the cooler lines as well. After 20 minutes of run time the cooler lines are much hotter than the pressure port line. I have worked with alot of tech's that say to put it into the pan or the return cooler line. After almost 12 years of dyno testing transmissions I believe they are correct. I believe a drain plug kit for a oil pan will work with a 1/8 pipe plug or you get a T and mount it into the return line. If you need one I'm sure we can hook you up!

Vince,

Im curious as to why putting the sending unit in the pan or the return line from the cooler is best? Wouldnt putting the sender in the pan only give you the temp of the fluid in the pan rather than what temps the friction surfaces are seeing? Same thing with the return line from the cooler...wouldnt that give you a false low temp reading compared to what the gear train/clutches are being subjected to?

Wouldnt the best place thats feasable to put the sensor be the "hot" fluid out line going to the cooler since that would seem to be where youd get the most accurate reading of the internal components of the trans?

In theory we want to know what the temp of the parts are. You are correct here with your thinking. The reason for the locations that I believe to be correct is because in theory the cooler oil should help maintain overall trans temp. The oil in the pan is oil that the lube circuit has returned to the sump. The oil in the return cooler line is what feeds this lube circuit. As far as putting the sensor in the cooler pressure line or to cooler, this oil is being generated from the tc which with slippage is giving you tc temp not over all trans temp. This is a discussion that many disagree on and I have never seen a factory trans with a temp sendor in a main line pressure port. OEM units such as Ford, Dodge, GM and many others have always put their sensors in the return cooler line or in the oil pan. This should tell us something and if the main line pressure port was a better place or more accurate why have they never done this? I believe most do it because it is easy to install. Yes it will give you a reading but not a correct one. Had a customer ask me the same thing and we went round and round with this topic. He was telling me that if he drove his car for awhile and shut it off for about 15 minutes the trans temps were higher than when he shut it off. Also when it did get hot in around town driving he said that it seemed for ever to get the temp's below 200. Keep in mind this was in a TA with a 3200 vig. He took my advise by first removing the factory cooler and bypassing the factory cooler with just a 24000gvw B&M cooler. He said it was better but then moved the sensor to the return cooler line and said the trans has never run cooler and more consistent. I'm thinking this is the correct way to do it and proof is proof! Good luck to all of you. Just trying to pass along a little RND and facts. Vince
