Installing TransGo pressure relief valve. Here are some pics of the lifetime fluid and the pan. 102k miles.

 

I cannot believe that any car buff could believe in any "lifetime" lubricant.

 

I've never found one who does.

Since 'lifetime' was, is and will remain, undefined, it is a valid claim.

Washing up liquid would last for the transmission's lifetime

 

I just did mine as well, the valve is in the freezer to be installed today. My pan looked similar. 116k miles.

 

Maybe lifetime is ... of the warranty (or shorter if lawyers involved).

 

When it fails, that was it's lifetime's end. Kind of like the old tail light guarantee,, lasted as long as they could be seen when leaving the lot.

 

So I did a drain (got about 6 quarts) and then I dropped my valve body half and picked up another quart or so.

I reinstalled the pan and went to refill but could only get 4 quarts in there before it started overflowing so I put the bolt in.

I am assuming once I start it up it will flow through and I'll be able to get another 2 - 2.5 - 3 quarts in to equal how much came out? I guess it -really- drained after sitting so long?

 

Guessing your fluid was black like mine. Search for thread on refill/flush procedure. About four quarts go in pan without engine running. When engine starts sucks up out of pan. You then add more until flows out of port. You watch temperature of transmission fluid. A good scanner will display it. I think the correct temp is 30 degrees C, but check that. Fluid expands with temperature. You keep port open and close when temperature correct and fluid stops dribbling out. Doing this does not get old fluid out of torque converter and innards of the transmission. Total capacity is 10.5 quarts. Fluid flows up through filter through transmissin and torque converter, so new fluid mixes with old.
You can kind of flush by repeatedly filling pan before doing temperature dependant final fill. After several times the percentage of old fluid will be much less. Other option is to disconnect where fluid goes through the radiator. Fluid flows from bottom inlet to top. Top is easier to get to. I took out fan for room for wrench. Disconnect transmission cooler at top. A 3/4 inch thread PVC coupling (like used for sprinklers) will screw on. It is not the exact thread but because PVC soft it will not damage hard metal connector on radiator. Start up and run for 5 seconds with a buddy watching what comes out to catch can. Running through gears with foot on break. After each 5 second run, refill pan until fluid that flows out turns from old to fresh. Then do final fill procedure above.
Some may shout heresy, but I use Vavoline ATF and not the ZF Lifeguard. The bottle says it meet the same standard as Lifeguard. Several long posts disputing it is a substitute. I bought a 2003 XJ8 with 100,000 miles and did the flush as above. Sold at 150,000 miles with transmissin working fine.

 

Finished flush of the transmission. Used a little over three gallons of AFT. I refilled the pan 4 or 5 times. First fluid in catch bucket was black, then black with hints of red, then dark red, and finally red and clear just a hint darker than new fluid. I'm no transmission expert, but I understand the fluid goes pan ==> filter ==> pump ==> valve body and torque converter ==> cooler ==> pan. I think mixing the new fluid with all the old fluid in the torque converter is what takes multiple times to get to the end result. Also, before started blew compressed air through top radiator inlet to clear old fluid in out line from transmission. Since pan was off I could see old fluid dribble when I did this.

 

Not wanting to start another 'WHAT FLUID FOR ZF5HP24' but there is no RED fluid compatible with the ZF5HP24.

But you did
Vavoline Multi-Vehicle AFT claims LT 71141 compatibility. Respect your opinion, are you good with Mobile LT 71141 or Febi LT 71141?

 

I have never tried Mobile LT 71141 but have used Febi 29738 Auto Trans Fluid lately.

Years ago I worked on a lot of New Beetles, Jettas and Passats with 01M and 01V gearboxes that use the SAME fluid as the 5HP24.(G 052 162 A2)
The VW dealer would deliver NEXT DAY to me so I did use that when I needed it 'in-a-hurry'.
When I worked at the Jaguar dealer I only used ESSO LT71141. (packaged in Jaguar boxes)

 

I'm guessing packing in that box doubled the price. I bought injectors for my 911. I think from AutohausAz or PartsGeek. Website listed Bosch and Porsche brand injectors. Porsche double the price. I called and asked what's the differenence. Answer: the box. Exact same Bosch injectors.

 

Liqui moly 1200 atf

 

I don't know about the USA but in the UK the Mobil LT71141 is widely available and only $18 a litre and was the fluid recommended by Jaguar when the X100 was released. It is all I've ever used for the early cars. I use the relevant Lifeguard fluid for later models.

Now you've done it!! Last time I mentioned that I got roasted for being an irredeemable cretin!

I've used LM 1200 in all my German 5-speed auto boxes and it's been working fine for tens of thousands of miles.

 

Reviewed shop manual. For starting top off must be under 30 degrees C and must close up before 50 degrees C.

 

Yup used it in my xj8 the transmission working as it should
You can't go wrong with LM or mannol
