Harvey,

As of old, by averting members attention towards an endless barrage of nonsense and related images, you continue your efforts to hide the real issue. I will stick to facts and again disclose that you are again and again wrong.

With facts in mind, I took a drive this morning in my new toy, a Mazda MX 5 Miata. As I have said before, the SVX is an old man’s Grand Touring Car in my book and not my cup of tea on the fun front. Out in the open air again, driving something a little more frisky, I called on transmission specialists who are used here by Subaru dealers, and as a result are well versed in the E-4AT system. My object was to obtain a further back up opinion, in respect of what I had already learned from others and had also analysed myself.

The discussion was interesting and informative. Each and every statement I have made regarding the operation of solenoid “A” and “C” in the 4 EAT transmission was confirmed as exactly correct. A set of solenoids, moments before taken from a transmission being overhauled, was thrust at me with the comment, “cut it open and see for yourself.” Detailed manuals were also produced as further proof of the pudding. Nice guys.

The components of the solenoid valves are housed within shells well and truly swaged as one piece, so that some arduous grinding was required to explore their inner secrets. But first the “A” solenoid was pressurised, both de-energised and energised. The taste was bad, but the confirmation that the valve is indeed NORMALLY CLOSED was rewarding, even though not unexpected.

The first item of interest was a quite strong spring, which clearly holds the valve shut/closed against a seat, when NOT ENERGISED. There was also evidence of a probable pre-set adjuster for the spring, used during manufacture but otherwise fixed solid.

Second of interest was the very short available travel, (approx. 2 m.m. max.) and the fact that as anticipated the design constitutes a purely on off device, pulled open by means of a solenoid. There is absolutely no possibility of partial opening/closing as claimed by Harvey, even if this were electrically possible, which it is not. The weird concept, for so long and so often stated by Harvey, is confirmed both impossible and stupid.

Furthermore, without my prompting, it was pointed out to me that the usual items which follow a pulse width modulated solenoid valve, will not be affected by any possible ripple in the line pressure, because of their inherent reciprocating weight/mass, even if the smoothing provided was ineffective. A compressed high frequency fifty cycle ripple, is far from a tidal wave. In point of fact it would appear that I have drawn too much attention to the aspect of smoothing.

Also mentioned by the experts, was that some minor details vary between manufacturers in respect of the same component, but the principal of operation is always the same and therefore the samples provided were exactly indicative.

The dropping resistor circuit was discussed and it was agreed that I had explained this aspect correctly and in greater detail than the instruction manuals, which simply outline the basics.

Harvey’s anticipated next move will probably be to state that his knowledge far exceeds that of all others. Or he will he accuse me of being a liar in respect of the information I have received. His problem is that like me, members can easily obtain and dissemble an A solenoid for inspection, should they be in any doubt.

Whatever, I am sure that Harvey will have been in the interim rejoicing in anticipation of again posting more derogatory, haughty, sarcastic, comments from his ivory tower, or glass house, but not his current deep hole. Having dug even deeper he must now climb out of it.

Myself, I leave my statements presently under criticism intact, but possibly subject to expansion at a later date.

When the dust settles to put it nicely, there has been some ****e pushed up hill here, I will also comment regarding other useful evidence I have uncovered in respect of solenoid failure leading to transmission disaster. Again ****e is involved.
