I've been researching on my own to attempt to figure out why a solenoid change would have been made, and I can't figure out why they would change it like that. The different wire colors don't surprise me as they could have switched manufacturers, or sometimes the current manufacturer just decides to change the wire color for no reason. I've seen stuff like that happen before.

The opposite is not the case. Based on the facts at hand, the evidence that transfer solenoid C in the JDM/AU transmissions was changed to a N/C design in later models is absolute. Here is the proof: It is undisputed that all US transfer solenoids are Normally Closed. My Subaru dealer provided the following part numbers for the transfer solenoid: PN 31942AA 061, US up to 05/95, transfer solenoid PN 31942AA 090, US 5/95 to 11/96, transfer solenoid I was told that 090 DID NOT supersede 061. Japanese and Australian parts catalogs provide the following part numbers: PN 31942AA 050, 09/1991-01/1994, updated by: PN 31942AA 051 02/1994-10/1994 PN 31942AA 061, 11/1994-04/1995 PN 31942AA 090, 05/1995-11/1996 These later two Japanese and Australian-spec VTD transfer solenoids are the same PN [exact same part] as US-spec N/C solenoids from 92-97. The change to N/C solenoid from a N/O is the reason that a TCU for an early VTD transmission will not properly control a later VTD transmission. This fact was determined independently and almost simultaneously by Harvey with his late UK-spec box controlled by 'early' programming maps, and by myself with a late JDM-spec box controlled by an early JDM TCU in our US-spec '92 Peacock Blue SVX. Why the change? That in fact, is the question without an answer.

Re: Gearshift Maps
Greetings,
“This fact was determined independently and almost simultaneously by Harvey with his late UK-spec box controlled by 'early' programming maps,” Without the information requested in my posts #204 and #206 recorded, the information so far available is nebulous. Nothing has been proven and it is indicated that an after market EPROM is the cause of the reported problem/difference. “and by myself with a late JDM-spec box controlled by an early JDM TCU in our US-spec '92 Peacock Blue SVX.” Are you advising on the basis of experience with your own car? Particularly interesting is the fitting of a JDM transmission in a US spec. SVX. Details would be appreciated, including specific before and after results, and how, when and where there was binding. At this point you must appreciate that the only proof is, that you corrected a problem by changing the TCU. In point of fact the early TCU could have been faulty.

Hi Trevor, Please note, I have only posted three times in this thread. The one and only purpose of my first post was in response to your one post, to offer substantial and unrefuted proof that late VTD boxes were IN FACT fitted with a N/C transfer solenoid. This statement was based on US/JDM/UK Subaru part numbers at hand. Again, based on information from Subaru dealers around the world, not based on my experience, not based on the experience of others, the part was changed, for reasons unknown to date. No, I am not advising, or giving any advice, on the basis of experience with this particular car. This is not the venue. As this thread is highly significant and important, Phil's Gearshift Map thread, I'll step out now, and let the discussion and debate resume with that theme. Thanks :-)

All we have is a change in part numbers, which lack an associated description of the part. There is no verification of a change from N/O to N/C. The change in number could be for many non related reasons. I have hearsay evidence which contradicts what you have been told, so must leave the matter in abeyance. Whatever, thanks for the information, Trevor.

Yes, there is verification, from Subaru dealers worldwide! This is not personal opinion. This is not hearsay evidence. This is factual, numerical, unrefuted verification and proof. Please do not misunderstand; I'm most interested in the fact that you and Phil have accurate facts with which to make logical and proper conclusions, thus the reason for posting. We remain fortunate that Phil has a passion for TCU programming, wanting to collect and explore all SVX TCUs. Phil is one of our greatest resources here, without question. I'm been in email and phone communication with Phil for many years. My family and I were guests at Phil and Belha's home in the UK four years ago. He has an open invitation to visit California. Yes, I'm most considerate of Phil's interest in this and in all SVX details, as much, but likely more, than anyone here. I've asked a couple members with late JDM VTDs if their TCUs can be downloaded for Phil's use. I'm diligently pursuing data and facts to complete the record. Only then, once Phil has an opportunity to dissect late VTD programming, can a clear understanding of programming logic be established in relation to N/O and N/C transfer solenoids. I would agree with you, that the change in part numbers, in-of-itself, is not proof enough. However, Subaru part numbers are universal. The fact remains, late VTD transfer solenoid numbers ARE the same exact parts used in US boxes. These US parts have been dissected my many members. IT IS CLEARLY ESTABLISHED THAT THE LATE VTD PART NUMBERS ARE N/C PARTS, THE EXACT PARTS USED IN THE US. Unless you can prove that the part numbers on hand, received from Australian, Japanese, and American Subaru dealers are fiction, you should accept the facts presented and move onward, so that a clearer understanding in this matter will enable you to provide accurate advice to our members. Verification for you must come from Subaru dealers via parts numbers. I can PM a VIN for a S3 if you would like to confirm the solenoid part number in this late application. I'm sure that you have access online to verify the US part number for a numerical comparison. Any US member could assist. Based on the evidence, the fact that late VTD boxes are fitted with US-spec N/C solenoids must be accepted and established to fully understand the compatibility of parts, and/or programming, for all SVX markets. Take care, Ron

Re: Gearshift Maps
I had to order some components for another kit I'm sending off to the assembly house so while at it I'm ordering the components for a couple hundred ttl232r adaptors to send off to the assembly house too.
Here's a print screen of the routed board. |
