Down side?
I pulled the transmission module fuse in the large engine compartment fuse box. I went for a test drive and the transmission performed beautifully, but it was driving well before so it will take more driving to see if anything has significantly changed.
The hard reset issue... I have been seriously considering doing that simple procedure on my car and my wife's, just for a clean start. Is it possible for problems that did not exist before to pop up? My wife's 2004 XJ8 transmission was "re-flashed?" by the dealer just before we bought the car; would a hard reset effect that?
Sorry to have YET more questions...

Installing the Transgo 5HP-24-PR valve today. the old valve and bore did not seem to be worn at all, and the trans was shifting fine, but at 95,000 miles I thought this would be worthwhile insurance.
I will add also that I found the spring pressure behind the valve plate to be pretty significant, so use care with a clamp in the center you can loosen slowly after removing the screws. The PR is the stronger of the 3 springs so you can favor that end with your clamp.
By the way, the fill plug can be tough to remove, so I recommend that be your first step before you drain any fluid (loosen the fill plug to make sure you can do so). I had to put a short breaker bar on a wrench to get it loose. I had no problem getting a wrench up in there with the 8mm. See below for the approximate angle to clear the exhaust pipe.

It's also "fun" trying to check the trans oil level with the car warmed up and the red hot exhaust pipe only 2 inches from the fill plug.
@64vette how did the Transgo job go? Did you see any difference in the shifting? Did it take a while for the shifting to return to normal?

Allowed to drain overnight with the valve body removed. It took 4L to fill dry, then once running and warmed up it took another 2.2L to fill to the "steady stream" point so, 6.2L for PR valve, and filter change.
Have not driven it yet as I am inspecting and detailing undercarriage right now, and will be attempting to check differential fluid. I think cold country folks would be amazed just how clean and rust free a CA car can be underneath, even after 15 years. Edit: Differential Fill plug was actually pretty easy to R&R, I think the coupe may be easier to get to than on the convertibles although there is a substantial cross brace and the sway bar to maneuver around.

In doing this procedure, how critical is it to use the ZF lifeguard5 trans fluid? Is there any other substitute available? The biggest turn off of doing this job (aside from the fact that I've never touched a tranny before) is the cost of parts. Is there a more cost effective fluid available that meets the ZF specs?
Thanks, B

Personally for the extra $70 dollars or so for the fluid change that the ZF Lifeguard 5 costs I would rather be certain I am using the correct fluid. Seems to be more suggestions on this forum for Lifeguard 6 substitutes (mainly Mercon SP) but I did see someone claim that Mobil 1 ATF is equivalent to Lifeguard 5. You can buy the kits with Lifeguard 5, filter, gasket, and also fasteners on eBay. My pan fasteners were fine but the wave washers had collapsed some so I used new ones, but that adds yet another $70 or so. I think for those who flush the trans (there are pro an con opinions for that) a large amount of fluid may be consumed which would make the cost differential more significant.

Be interesting to get a confirmation from Castrol.
I saw a letter from Castrol on the BMW forum where they state that the Transmax meets the requirements of ZF Lifeguard 6, but could not find anything specific about Lifeguard 5. ZF does state the two are different.

Interesting that Castrol states the Transmax does not meet Ford Type F or GM Dex VI requirements.

Drove it about 40 miles today and the shifting is smooth, as others have also noted after the transgo valve installation. I will add that it was also smooth prior to the installation, so basically I notice no difference. I did this to hopefully prevent the problems that can occur due to wear of the original Pressure Valve and/or bore, so it was not to correct a harsh shifting condition.

The valve replacement was pretty straightforward - except the filler plug was hard to find.
THE FILLER PLUG IS ON THE RIGHT SIDE, TOWARDS THE REAR, ABOUT PARALLEL WITH THE EXHAUST PIPE!
Sadly, the valve replacement did not fix my loss of first gear problem.
For the price of a tranny rebuild/replacement, I'm looking at a 2002 VDP, garaged, original owner, 82,000, $4900, silver. Any thoughts?!

FWIW, I had a rebuilt (Ericcson) installed and in the car for less than 3200 USD. 100K mile warrantee, ZF factory rebuild shop.

Here in Aust. it's the same oil known as Transmax-Z with full 71141 spec.
I have used it in my trans for the 10 years I have had the car.
It is hellishly expensive here at $94 AUD for four litres ;o]
My car has covered 214,000klm now and had the trans completely rebuilt
at 130,000klm.

ok, back story is the car sat for almost 2 years as the elderly original owner was too sick to drive. i was given the car in january and almost straight away the usual gearbox problems started, the occasional delay into D or R from N and the typical thump and also the dreaded no gear followed by a huge thump after slowing down to a stop too fast.
i dont drive the car much, probably 1000 miles since getting it and i'm surprisingly gentle during the potential problem moments.
i spent ages researching the web and read all about the drum failures and valve bodies in the 5HP24 gearbox family. the general consensus was that wear in the pressure regulator valve allowed excess fluid pressure which makes the A drum pop its seal.
i decided to do a fluid and filter change using a Meyle kit from ebay, £130 with new bolts, magnets etc. the fluid came out black and really stank, of course it had never been changed and probably never topped up in its life, thanks stratstone for your comprehensive full service history..
with the pan off i checked the valve body for signs of the potential cracks that i read about, there didn't seem to be any so i fitted the new filter etc and gave the car bit of a drive (i went on holiday in it)
as expected the original problems were still there but slightly worse.
during my original research on these problems i came across a company in the US called Transgo that makes specialist transmission parts including a pressure regulator kit for the 5HP24, they call it 5HP-24-PR, it cost me around £80 with shipping and VAT.
Transgo state it won't fix a broken drum but can help avoid it along with 'runaway pressure, harsh shifts and kick-down bang.
as my drum isn't broken and i have no fault codes etc i thought it wouldn't hurt to try it.
the kit comprises a new valve, spring and special seals and can be fitted with the gearbox on the car.
it took me probably 4 hours start to finish to fit, i reused my fluid as it has done only 400 miles and looks very fresh but i did decide on a filter.
i took it for a drive and it does seem to have worked, all the shifts are very smooth. of course time will tell if its a permanent fix.

Like weatherforcast, I received all three printed sheets with the kit I ordered from Transgo.
Cheers,

I did a thread on the procedure. There is a link to the PDF in the thread.
