Transmission output speed sensor

Ok this is what i found in the aw4 troubleshout in 1996, the AW4 transmission added a front input speed sensor and the rear speed sensor changed from a 1-pulse/rev reed sensor to a 4-pulse/rev magnetic sensor. For this reason, if you are planning a swap you should try to keep the same year wiring harness and computer.

Ive have a 92-93 wiring harness and tcu but a newer styler transmission. Trying to figure the best possable solution. If anyone has done this let me know.

Could get the newer computer and change the older style tcu connecter to the new one by changing the pins and connector and wiring up the input speed sensor.

Or can you modify the newer style output speed sensor or modify the reluctor ring on the output shaft. :rtft:

Ok so if anyone ever does this swap the solution is easy!!! Dont worry about the input speed sensor. Get the older single pulse reluctor ring and swap it in the extension housing. Need the older styler sensor and hold down. Make a simple bushing to make the snsor fit and grind down the hold down bracket. Put everything back together then done.

The prooblem with the other ring is that its telling to tcu that your are going 4x as fast as your really going and pretty much shifts straight to overdrive.

you could also make a "divide by four" counter from about 10 bucks of electronics.. depends on what is easier.

either way glad you got it working.
