Found 85910-18010 inside over the radio, but it is RELAY ASSY, CIRCUIT OPENING (FOR EFI)... not transmission part unique for EXY10 Found 2 cut cords near the BLOCK, JUNCTION (82671-10020). Compatible fuse box /82671-10021 possibly those wires are connected to this overdrive button... -> research need soldering with button and insulation, cover found one yellow wire in mid panel, disconnected |
|
"L" type transmission installed is not electronic controlled like "E" type, this button implements manual control over speed number 4 disable 4th speed/enable 4th speed = main function |
|
On the changed meter panel have indicator "O/D OFF" on. button "overdrive" switch located in handle of selector, goes to 4-pin connector (another 2-pins are bulb), near Computer, shift lock control /85933-10010 |
|
on A242L-712 have module (T08 selector position) neutral switch , SERA01 SERA02 /84540-16030 , SERA03 /84540-16040 from diagram 84-01: SWITCH & RELAY & COMPUTER (car model EXY10-ACPGH) |

As expected, MCU should read the following data: speed sensor(s) {2}: No. 1 speed sensor is mounted on rear of instrument panel; No. 2 speed sensor located on transmission temperature coolant sensor /89422-20010 or /83420-16020 /89428-20060 or /89428-12160 throttle position sensor: has 3 pin socket (original EXY10) /89452-14020 (SERA01 and SERA02) or /89452-12060 (SERA03 and many other) selector position (neutral) /84540-16030 /84540-16040 stop pedal switch SERA01 SERA02 /84340-10020 (replaced /84340-28010) or SERA03 /84340-32090 (replaced /84340-42010) (other Toyota switch models /84340-06020 and /84340-28010) -> replaced switch stop lamp /84340-32090 overdrive switch /84722-18010-03 /84722-26080 |
|
For "E" transmission need extra wiring to: SWITCH ASSY, PATTERN SELECT /84720-32041 (EL43 or EL44) /84720-16030 (EL54) SENSOR, SPEED /89411-20040 ROTOR, SENSOR /89414-12010 As for AT and engine mounting brackets: 1st: original part replacement 12371A INSULATOR, ENGINE MOUNTING, REAR /12371-11360 is given for EXY10 the same as for EL54 and EL43 2nd: 12362 INSULATOR, ENGINE MOUNTING, RH(FOR TRANSVERSE ENGINE) |

swap-ready 89661 COMPUTER, ENGINE CONTROL list: From Cynos EL54 (EL54-DCPVH and EL54C-DKPVH; GEAR SHIFT TYPE: 4FC; AT should be A244E): /89661-16450 (211000-3790) -> big size -> got this *priority, newmost (2?? ????) but several extra labels had seen found on EL54 89661-16450 "engine control" units: "E c5a 89660-16550" (some computers have "LF" label... possible for A132L or A242L mentioned in part catalogs). from COROLLA2 CORSA/TERCEL EL43, CYNOS EL44 (EL43-CGPVH and EL43-AEPVH and EL43-AGPVH and EL43-BEPVH and EL43-BGPVH and EL44-DCPVH 12.1992-08.1995) /89661-16240 (211000-0970) and earlier (MA-6300; has extra 12P) -> same size, but hard to find on market There are ECT (electronic controlled transmission) models also: from CYNOS EL44 (5EFHE EL44-DCPVH 01.1991-12.1992) /89661-16130 (MA-5890; extra 12P) buy this and get pinout (below) A242E? TERCEL EL43? EL52? So, best upgrade AT for Sera engine is E-EL54 Cynos parts, but they are same rare as Sera's |

Additional sensors from EL54: MAP /89420-16100 /89420-16070 -> unique cooliant temperature /89422-20010 -> same as EXY10 air intake temp /89424-12010 -> same as EXY10 throttle position /89452-22090 -> many similar |
