Squeaky's wrestled and baby birds (that can read and maintain focus for a few short sentences) now fed.

3-years & 10-months later and I have at long-last managed to find and add the AisinAW identification codes for all of the transmissions listed.

Should you be considering fitting a V8 1UZ-FE engine and/or transmission into your Supra. The speedometer signal in the early LS400 A341E Lexus transmission is not compatible with the Supra speedometer. Further details in this thread; http://www.mkivsupra.net/vbb/showthr...1uz-conversion This issue can be remedied using a Speedometer Signal Interface such as this; http://www.dakotadigital.com/index.c...rod/prd126.htm Prefferably, avoid the earliest versions of this engine and transmission, which can be identified by the 50042 ECU and A341E transmission. Much less conversion work is required with the later models, which can be identified by the 50350 ECU and A342E transmission.

Aristo transmission is an OE components plug & play fit into T.T. Supra by using; Lexus SC430 prop front-section and T.T. auto prop rear-section. Alternatively (and my preference), swap the Aristo prop-flange for a T.T. auto prop-flange as explained here. http://www.mkivsupra.net/vbb/group.php?discussionid=223&do=discuss

When using a transmission from an alternative Toyota/Lexus, the 4-different designs of transmission prop-flanges, 3-different sized bell-housings, 2-different sized donuts, 2-different prop centre-joints, 2-different transmission-mounts and several different lengths of vehicles; results with many variables Further to the "recipe" I have used for my own Supra and many N/A-T Supra's, there are other combinations of components when using alternative engines and/or in alternative cars However, most of the owners of these alternative working combinations have little or no idea which components they actually have? Consequently, I can't feed this information to the Prisoner Messaging baby-birds that want-want WANT it I have listed which parts of these combinations that I know of and have requested the remainder, as & when this missing information is identified, volunteered or exposed by common denomination, I'll update it below

Not much of it makes much sense, we'll get to the bottom of it over that cup of tea.

SupraStick is set at 16 blips per rev from speed-sensor, so if the X4 is not done electronically, it must from the gear-pair? It is why your's has 4 x times more again that's the mystery?

Have you identified what is multiplying the signal X 4? I believe that the ECU multiplies the transmissions 4 blips per rev to 16, are both of those readings pre-ECU?

You have just exposed that the Toyodiy, "New - Search by Part Number" function (that I used), doesn't work properly? The different gear-pairs that you have correctly identified, thank you, correspond to the different differential-ratio's and different OE wheel size & tyre profile combinations in the different cars listed. This gear-pair difference mechanically adjusts the resulting electronic speed-signal to a "common-pulse" for the ECU's and speedometers. For instance, the resulting speedo-error after swapping an N/A A340E-GE box that had 4.083 diff speed-sensor gears, for a Hybridised T.T. A340E-GTE box that has 3.769 diff speed-sensor gears when still running with an N/A 4.083 differential; is around 4.5%? raised on speedometer and with an influence on moment of gear-changes, becoming lowered by around 300? engine rpm. (plus or minus influence from whatever sized wheels and tyre profile differing from OE?) I don't know what differential Paul's Supra is running and can't remember the wheel/trye - size/profile combo?, but if it has a T.T. auto A02A or B, that I would suspect, the resulting final-drive ratio compatibility shouldn't be far off? I haven't wasted my time with/by chasing after all of the different before and after wheel measurements and tyre-sizes & profiles and differential final-drive ratio's and then bent my mind with complicated mathematics, because, my ready-reckoning reckons that these differences are not different enough to cause the apparent far larger discrepancy?

This would give the definitive answer.

Picoto trumped my findings with this much better one. Thank you. http://wilbo666.pbworks.com/w/page/41678224/2JZ-GE%20JZA80%20Supra%20Engine%20Wiring

This is the AEM pinout diagram for Supra, which is the clearest ECU wiring example I have found. https://www.jegs.com/InstallationInstructions/0/017/017-30-1100.pdf

You could i.d. the exact age of your A341E transmission from the Aisin Warner plate, see bottom of page linked. http://www.mkivsupra.net/vbb/group.php?discussionid=153&pp=10&page=2&do=discuss Then you could i.d. the sensor you have?

Because I've never found or heard of any speedometer compatibility issues resulting from swapping transmissions of different dates into Supra's. I can't see it having a different pulse signal, just a superseded component? http://www.toyodiy.com/parts/xref?s=83181-24040&mE=on For instance(s), Delboy52's Supra is a 93 N/A with a later A343E U.K. T.T. box and bluesonic94's is a 93 N/A-T with a later A340E J-spec box.
