Want to get my speedometer back after a th400 swap
Want to get my speedometer back after a th400 swap Anyone know what I can do to hook up my factory speedo to my turbo 400 trans. It's a 1998 z28 with a modified 98 harness and an 02 PCM. I do not have abs now. I would like to use one of the front wheel speed sensors to get my signal for the speedo. Anyone done this? Thanks
The speedo in a 400 goes in the case not the tail. Prolly has a freeze plug installed there.

Why does everybody try to get all elaborate? The TH400 came in vehicles with electronic speedometers. All you need is the STOCK reluctor wheel and the STOCK vehicle speed sensor. The only thing you need to modify/change is the plug on the harness so it will plug into the older style VSS. Hell, if your car was originally equipped with a 4L60E (or an 80E for you truck guys) then you don't even need to do any tuning. It boggles my mind that people are jumping through hoops or trying to reinvent the wheel when it comes to getting the speedo to work after a TH400 swap. It's soooo simple.

Because some people have the tranny's without the internal sensor already in there car. Obviously if the sensor or wheel was there they wouldn't look for other ways.
Holy hell, so buy it and install it! It's a lot less hassle and expense then buying an aftermarket reluctor wheel set up and fabbing up some brackets to hold a sensor. Really, it's not hard and you don't even need to pull the tranny to do it.
I'm going through Dakota digital with these 2 part numbers.

Lonnie at Extreme Automatics built my 200-4r with a stock 4l60e speed sensor in the tail. ~$150 for the work and sensor.
