I am going to swap a 400turbo into my 90 c1500 the tranny ha a ct-69 plate on it. Does that mean it is 1969? And if so will it work in my 1990
My car has 200000 miles.
My car has an automatic transmission.
The vehicle identification codes on a GM product like the Turbo 400 transmission you’re looking at indicate three things. The GT indicates the application of the transmission; in this case Chevy Truck. The 69 indicates the manufacturing year; 1969 as you’ve guessed. The last numbers will indicate the serial number of production. You might want to have a professional mobile mechanic inspect this transmission to determine if it’s rebuilt and in good condition and if it will work with your 1990 C1500; as without verifying bolt patterns, flywheel and torque converter set up; it’s not possible for us to give you a yes or no answer on whether it will work.
