Dear, I have problem after transmission rebuild. My car will not shift from first to second gear properly. It change after it reach twenty to twenty five km/h and it rev 3000 rpm to reach twenty five km/h in first gear and at eighty km/h. My car has to rev to 3000 rpm and not change to fourth gear. When I try to check the code using my elm mini with my phone it show P0741, P0748, C2B18, C0307, C0100 and P0056. What is that problem? The workshop man seem no idea about that. Thank you in advance.

Most of these are related to valve body electrical problems, shift valve, converter lock up clutch check and clean all terminals in the harness plug at the transmission and make sure that this plus is tight see if that improves matters.

It sounds like you have a shift solenoid that is not working. I would test through the winding's to see if there is continuity. Also, check the four fuses that run the system. You can see which ones from the diagram below.

Here is a guide to help us get started:

Also, there is a ranger selector switch I would test as well.

Here is the transmission wiring diagrams so you can get started.

Check out the diagrams (below).

Please let us know what happens.

Cheers, Ken

It is beginning to sounds like you have an internal lip seal or clutch pack that is going out. It might be time for a rebuild.

Here is the location.

Please run down this guide and report back
