CEL light came on the other day. Runs and drives fine, transmission shifts fine also. Went to AutoZone and had the code read which was P1700. They had no other information to offer and reset the CEL. I was driving today and was coasting to a red light, the light turned green before I applied the brakes so I gently accelerated and immediately the CEL came back on. So I'm guessing it is the speed sensor. Thanks EatonKyleH for the info! Does anyone know what the part number is? I've looked all over and can't seem to find it.
I will verify that PO770 means new tranny. Hopefully your fix is good.
Do one of you have a P0770?
it's P0770 - Shift Solenoid E Malfunction
anyway if so I can send you testing procedures if needed
I just was unaware of why that code is being brought up and if you needed any info on it.


My sensor came in today from toyotapartsales.com, but when I crawled underneath the truck I couldn't find an exact spot to put it that matches. It looks like it should go where the blank cover is, not where the existing one is. Can I put it there? How would I cover up the other (old) one if I did that. Or is there a different speed sensor for a '96. I did buy an OEM 89411-50010 sensor. Note: The plug does seem to match, so maybe I can just move the sensor to the other spot and leave the old dead sensor where it is?
Thanks guys for your help!
Kyle, The Parts department is telling me the part in my picture is a Transmission Revolution Sensor, p/n 89413-08020. Do you think that would throw a P1700 code as well?
