  1. Inspired by @onespiritbrain I looked into a straight forward solution to cold weather starts while using an external cooler and adding a temp gauge. Nothing fancy but I feel like I may end up using something like this. The valve would be manually actuated from inside the cab and the gauge could be mounted in a variety of places. Would require: -Temp gauge kit -simple 3 port manifold -3 way diversion valve -brass T fitting -hose and clamps

  2. I run my cooler independent of the radiator. I tow an 18ft toy hauler and when its loaded the weight hovers around the R50 max recommend capacity of 5k lbs so I wanted dedicated HD cooling. I don't currently have a temp gauge but I definitely want one. I monitor everything through my OBD2 real-time when towing but it doesn't have any trans readouts. The only downside of bypassing the radiator for me has been that when temps are low, less than 32°F, for first few miles of driving after a cold start the transmission wont shift into OD while it gets up to operating temps. This has barely been noticeable since I cant reach any significant speed (legally) on the country roads around my house before getting on a highway. Other than the cold start scenario there have been no adverse effects of this setup. As for the temperature controlled valve system- I personally would not ever trust a system like that because if it fails and I'm towing or miles away from any civilization and services on a 4X4 trail the transmission failing could potentially put my family and I in serious trouble. Now, on the other hand, a manually actuated valve @onespiritbrain mentioned is appealing and pretty easy to do. Same design and functionality of older vehicles with a manual choke.

  3. Just a few thoughts and questions. You know how the driver's window has a function where you press it down once and it auto rolls the window down, but the other three have to be held? Anyone ever tried to mod this so all four work like the driver's window?

  5. Ok ok ok... that’s not normal slipping. That is something else. Someone who knows more about this will have to chime in. It sounds to my like an oil pressure issue which is not present at higher RPM— higher oil pressures!

  6. If I give it a lot of gas it’ll shift just fine, also when I’m on a steep hill it’s fine

  8. If you bypass the radiator and use only the cooler then you can have trouble with trans temps being too low during very cold ambient temps since your not getting the heat from combustion at the radiator. The radiator kind of acts like a heater during the winter. If the temp is below 125degF (I think) then the torque converter will not lock. At best you will have lower gas mileage and at worst the oil is going to degrade from shear forces inside the torque converter leading to premature wear since the normal oil life cycle will not be as long. The solution is to create a system that will divert the oil from going thru the cooler when the temps are below 125degF. That requires a controller to look at the oil temp and actuate a valve (or valves), bypassing the cooler and routing the oil straight back into the trans. The parts need to be reasonably high quality since failure will kill the transmission and quality is expensive. Especially when you are looking at parts that are generally used in industry and the usual customer is a company instead of an individual. I can’t find a directional solenoid valve under $150 and those are only 1/4” valves.. Temp controllers are usually quite expensive as well but I have found a few that are cheap. Anyway I haven’t had too much trouble with temps being too low here in Georgia but the dead of winter isn’t here yet. People that live way up north where ambient temps can be sub zero might never see 125degF trans temps. I’m thinking a high quality oil cooler bypass system is going to be a little north of $500 just to gather parts.

  9. Bypassing the cooler based on need is going to be expensive and there doesn't appear to be a way around it.. unless you want to plumb a hand operated directional ball valve somewhere that's accessible while driving... hmmmmm.. you really could do such a thing. You could have one of the outputs on the controller turn a lamp on to let you know its time to switch the valve to run thru the cooler and a second alarm with something audible and maybe a red lamp or something when the temps are higher than desired. You could even run with the valve in between positions and change it based on need... interesting

  10. I haven't run enough wire to have the gauge quite figured out by eye either, but I can compare the diameter of the conductor to the grooves in my wire stripper and get a ballpark estimate that way. I should probably print that chart and put it up somewhere. Different climate on this side for sure! And thanks.

  11. My 2002 QX4 had auto up/down on the passenger front window as well. May be able to jack some components from a junkyard QX4.

  12. Only the front driveshaft has a zirk stock. @Charlie_Brown has a WD21 which probably has more, but for you @AlabamaDan unless you have Moog BJ's or something you only have to worry about that front driveshaft. It probably hasn't been done in a long time so it'll take a lot of grease I suspect.

  13. Ford had a thermostat bypass for the trans coolers on later Crown Vics. Sounds like it was more trouble than it was worth; marginal benefit when it works, overheated tranny when it doesn't. I've got mine plumbed with an aftermarket cooler in line with the stock one, the same as your Q apparently. It's a fairly new rad so I wasn't worried about gunk, and by the time the slushbox pukes up enough material to clog a cooler, arguably the cooler's the least of the system's worries. I've never bothered to hook up a temp gauge for the transmission to see how much good this setup is or isn't doing.
