I have a 94 camaro z28 that came factory with the lt1 motor and the 4l60e. I bought the car with no motor no trans I have a 95 lt1 and trans. Should everything just plug and play or is something different on the trans that only 94 has some one told me that there is an external solenoid on the 94 4l60e that only that year has thanks in advance

I may be wrong but there shouldnt be anything different between the two transmissions that iv ever heard of...

I hope not I heard that there was an external solenoid on the 94 transmissions that u had to have plugged in other wise the tranny wouldn't downshift and you would have to put the car in park and turn it off then back on to reset the ecm

I think you r right. It is called a Pwm solenoid Which is for torque converter lock up which also adds an additional pin from 12(1994) to 13(1995)

Would it still work though putting a 95 tranny in a 94 car i know you cant do a 94 in a 95 car but never heard of going backwards. or is there anyway to make that tranny work

I'm not sure because you probably will loose TC lock-up

The 1994 4L60E will have a NON-PWM Style Pump, Will not have a PWM TCC Solenoid, Different internal Harness (4 Solenoid), and different seperator plate (1994/1993 trucks)
The 1995 4L60E will have a PWM Style Pump, Will have a PWM TCC Solenoid, Different internal Harness (5 Solenoid), and different seperator plate (1995 Only)
Both have the same 393 Valve Body Casting Numbers

To make it "correct" you can change the Separator Plate to a 94, remove the TCC PWM Solenoid, and change over to a (1993 4L60E Truck)/1994 style pump
I have been told that using a 1995 and up unit in a 1994 works with out any problems, but i have never tested this on my own.
