Brilliant, thank you. After this hurricane, I’ll start experimenting

On an aftermarket camera they are triggered by splicing onto the reverse light harness, which would be activated via the same switch. You could test this theory by applying +12v to the appropriate wire on camera circuit and seeing if the display...

I haven’t researched enough, but it looks like the camera is activated by a sensor that picks up when the transmission is in reverse. If I can find that circuit and wire in a switch… Maybe? I really don’t want to get into the head unit. I’ve...

100% doable with an aftermarket head unit. Not sure about doing it with a OEM head unit and camera.

Does anybody here have an opinion on the thread I started today about the rear camera option? I believe it wouldn’t be difficult to wire in a switch to turn on the rear camera at any time. Would be great for trailering.

I suppose it depends on the use of the vehicle and risk tolerance and financial situation of the driver/owner. If the GX is used as a short distance or regional daily driver, and the owner has a spare vehicle they can use in case it gets worse...

I agree that this is a band aid. What I’m going to find out is how far the band aid goes after doing a bunch of fluid swaps and adding the factory cooler. Can I get…10k miles? 15k? I think for a lot of people, just getting some runway back is...

AT205 will not do that IMO. It's a plasticizer, not a swelling agent. But - per my post buried up above - it does water down the transmission fluid and will likely change the viscosity and friction properties. Based on this thread I'd say it's a...

On my last F150 I had a button to a to ate the rear camera at any time. Really helpful with towing to check movement. Has anyone tried adding a switch to turn it on at any time?

Yeah, can break what’s already broke

Also a licensed engineer out of Arizona here who ultimately did a transmission swap cause I had the same codes/issues. I did some trails not long ago with some buddies and I was the only one who had no hiccups (chevy's and fords had electrical...

We're attracted to well-built vehicles - even if they have a fatal flaw or two :).

Lotta damn engineers around here 🤣🤣

Chemist, chemical engineer, mechanical engineer - or something else? :) In addition to "no downsides", a cooler is a dirt-cheap mod at $55 for a Hayden 678, or the bracket-included kit linked above for $185 (very reasonable price). In my archaic...

Simple question, why would a transmission shop be inclined to give anyone the recipe for a 500,000+ mile transmission? Since you mentioned accelerated aging and ovens, this is exactly where the Arrhenius equation comes into play. It dictates...

I absolutely agree that heat impacts materials. I'm a retired R&D engineer of medical devices. Every medical device has to go through accelerated aging to ensure all the materials can sustain a long shelf life of 5 years, 7 years, or whatever...

Every spec of rubber in my transmission was brittle, hard, and had shrunk. The old O rings had no stretch in them. It runs hot. Still does after the rebuild. (I’m assuming I’m missing something or it needs a new TQ or pump). It was running hot...

Agree with this. Before you decide to add it, monitor your temps. If you’re running sub 190, you’re prob fine. If you typically see 210+ on longer drives/interstate runs, you could already have hardening.

If it ain't broke, don't fix it. I personally would be concerned with over-softening healthy seals. The caveat is your transmission history. If it never had a fluid change by 100K+ and no auxiliary cooler w/ unbypassed thermostat the seals...

Are you planning to add the Toyota cooler or a Hayden cooler?

We had the solenoids replaced in April 2025 on our 2011 after getting the codes. Zero issues since then until today (about 12,000 miles). It has been driving fine. I cleared the codes. AT205 here I come. I will probably also add the cooler. I...

I have a 2010 GX460 with 140K that won't shift past 3rd gear until it's warmed up. I have been using the sport shifting and clearing the P2714 codes to get around it the issue. I tried changing shift solenoids, trans fluid w/filter and nothing...

Check the valve body and solenoids. I thought there was something different in the rebuild kit I received from Cobra between the E/F

Clear rubber/plastic hose (somebody here will recall the size, I think 5/8) and a funnel. Drop it down under the hood by the exhaust on the passenger side. You need like 8’ of hose. When you put the AT205 in, chase it with an ounce or two of...

Don’t let me understate the performance improvement of AT205. Amazing product. Likely saved this truck from the sale barn. My truck has issues outside of AT205s reach.
