Replaced the transmission and it's a cd4e, but when shifting from second to third it kicks and bucks wont engage third. What could be the problem? Could the computer need to be reprogrammed from when the old transmission blew up? Thanks

Good morning,

Yes, the TCM should be re-flashed with the current programming.

You can either take it to a shop that can perform this or to the dealer who will be the highest price.

Got it.

These codes are electrical codes related to the wiring harness inside the transmission.

You need a scan tool that can monitor the actions of the solenoids and switches.

After I replaced shift solenoids and had the codes read again turns out now all I have is a speed sensor code. Thank you for all the help. Hope this is all.

This code is not a component issue. It is a wiring harness issue.

You will need an advanced scan tool to access the transmission and check the voltages for the output speed sensor. This is not an easy one to fix.

Scan tool showed no signal. Already probed the plugs with ohms meter today. Both were fine the speed sensor was reading over 234 ohms.

The sensor generates its own voltage. You need to see if that signal is getting to the modules. My guess is that it is not.

If it is not getting to the modules how can I fix this problem? I work 45 minutes from home. I am going to attempt to get there tomorrow. Do you think I will cause more damage driving it at 50 mph?

Again, as I stated, This is a wiring issue, not a sensor issue. The possibilities listed all indicate a wiring issue between the sensor and the ECM.

You can try another sensor but I bet you have the same issue.

Hello again Roy, I looked at all the wiring did a ground drain test also got some interesting feed back I disconnected my brand new alternator and the car shifted well for a little while until the battery was going low. This is a robot car I guess one problem to the next.
