It's a 88

The manual trans was a gear driven speed sensor.

the S-10 trans is a magnet sensor.

is there a solution for this or just go to an aftermarket speedometer??
Which aftermarket will work also???

thx

Expert:  goodwrench9124 replied 6 years ago.
Ok, here is the problem, your 94 camaro uses a electronic speedometer. which requires a speed sensor, that is mounted in the trans tailshaft. now that you have installed a 1988 transmission, this transmission uses a mechanical speedo cable!!! basically the two speedo setups are not interchangeable!!!!

Reply to goodwrench9124's Post: Can i go to an aftermarket speedometer, if so who makes them??
Expert:  goodwrench9124 replied 6 years ago.
not sure i would go that route!!!! that would require a complete cluster change!!!! you might be better off, seeing if you can get a electronic speed sensor installed on the trans output shaft!!!!
Customer: replied 6 years ago.
Reply to goodwrench9124's Post: Where can i buy this speed sensor to go on the outside of the trans output shaft??
Expert:  goodwrench9124 replied 6 years ago.

you should be able to get a sensor about at any parts store. but you will have to get a sensor for a 1990 4L60 {700-R4} transmission!!!

Customer: replied 6 years ago.
Well, i guess it's worth a shot.
Do i have to change the plug that came off the manual trans, because when the mechanic plugged it in the speedometer went to 110 and then the car shut off.
thx

Expert:  goodwrench9124 replied 6 years ago.

i think the plug is the same, but you will have to get the sensor first, and then see if will plug in!! i think you should be ok!!
