97loudcut Posted December 11, 2006 Report Share Posted December 11, 2006 Okay now that I got my transmission temperature gauge I am wondering how accurate it is. On the cold night (about 20* out) my gauge was read 150* and this was doing a constant 75mph all the way back from Toledo on I-75. Today it was about 45* and I was driving in traffic and it was reading almost 170* I know the gauge is working because the temperature flucuates, but do these sound like accurate temperatures? I don't know if this makes a diffrence, but that GearLube additive I have in my transmission fluid claims to lower transmission temps.

19Cutlass94 Posted December 11, 2006 Report Share Posted December 11, 2006 They sound pretty good to me. Pretty much ( for a transmission ) anything under 200* is good. When you get close to 200* or go over... start to worry. Quote Link to comment Share on other sites More sharing options...

When I punch it, it finally stops moving and it sticks at "Rich" until I let off a little bit then it goes bonkers again. Quote Link to comment Share on other sites More sharing options...
THe_DeTAiL3R Posted December 11, 2006 Report Share Posted December 11, 2006 What kinda guage do you have? Where is it mounted (before/after the radiator?) When I went to Mr.Transmission the guy had a thing he pointed at my transmission and said it was at 250*... my tranny fluid does turn black like coffee but I dunno if it's quite that hot Quote Link to comment Share on other sites More sharing options...
Canada Posted December 11, 2006 Report Share Posted December 11, 2006 Thats normal ATF temp....hopefully you put it either in the pan or in the output of the cooler lines. Like others said, when it gets over a bit over 200, let off. I think trucks go red at 230....I think. The A/F gauge goes wacko because thats how the system works.....kind of annoying. I used to have one, never got the ATF gauge hooked up. Quote Link to comment Share on other sites More sharing options...
97loudcut Posted December 11, 2006 Author Report Share Posted December 11, 2006 The Tranmsiion gauge works off a sender that taps into a plug right on top of the transmission. It's pretty neat. Quote Link to comment Share on other sites More sharing options...

The fluid should never be black, and if your transmission is running at 250* it's FUBR'ed. I changed my fluid almost a year ago and it is as red as can be with no burnt smell to it. Sounds like your 4t60-e is on it's last leg. Quote Link to comment Share on other sites More sharing options...

About the A/F ratio I would say thats about right also. Quote Link to comment Share on other sites More sharing options...
terryk2003 Posted December 11, 2006 Report Share Posted December 11, 2006 yeah...that temp is about right...mine stays about the same...as for the A/F gauge...right on...thats how mine works when i watch the 02's...they stay constant @ WOT but they go all over the place @ cruise or idle or whatever...

19Cutlass94 Posted December 11, 2006 Report Share Posted December 11, 2006 Well the A/F should look right, its a fuel injection car thats computer controlled! If you wanted to, you could put a tranny cooler on. Quote Link to comment Share on other sites More sharing options...
Canada Posted December 12, 2006 Report Share Posted December 12, 2006 You just put it in the pressure tap? Hmm...I don't see why that wouldn't work. Its just that I would like to see the hottest possible temp....and thats right as it leaves the transmission for the cooler, because it just left the torque converter (the greatest source of heat) at that point.

GutlessSupreme Posted December 12, 2006 Report Share Posted December 12, 2006 The A/F still gets me. When I punch it, it finally stops moving and it sticks at "Rich" until I let off a little bit then it goes bonkers again. That's what it's supposed to do. That's why I recommended wiring in an on/off switch. Quote Link to comment Share on other sites More sharing options...

No it's a whole new big gold screw that screws directly into the top of the transmission inplace of the old screw. Meaning the bottom of the screw is sitting right inside the transmission. I can't imagine a better was to do it. Quote Link to comment Share on other sites More sharing options...
5speedz34 Posted December 12, 2006 Report Share Posted December 12, 2006 Canada, how would you tap into the cooler line though? Quote Link to comment Share on other sites More sharing options...
Canada Posted December 12, 2006 Report Share Posted December 12, 2006 I'd pry put a T inbetween the cooler line and transmission. What old screw are you talking about? There is a plug for the pressure tap...is this what it is? Or are you talking about some other random bolt? It needs to measure the fluid temp...not the transmission temp.

pwmin Posted December 12, 2006 Report Share Posted December 12, 2006 sounds about right to me. should be about the same as your coolant temp. although it might not be the most accurate, the pressure port (where you put it) is an okay place to put it Quote Link to comment Share on other sites More sharing options...
