Default Fault codes P0700, P1775, P0841

HELP.

The warning light on my 2006 Dodge Grand Caravan came on today, the faults on the systems were P0700, P1775 and P0841. Just before the light came on I noticed that the car was struggling to get into first when slowing down and when I accelerated hard from low speed the gear box failed to engage the lower gear. I have checked the fluid levels and all seem fine.

I had the transmission fluid and filter changed recently after it had some difficulties going from reverse to forwards when the engine was cold.

The van has done 121000 miles and has had a number of owners.

From what I have read the suggestions seem to be either the speed sensors or the solenoid. Any advice greatly received.

thank you

Have the solenoid pack tested as both of the codes (p0700 is just a code to tell you there are trans codes) relate to pressure switches. The solenoid packs are common failures.
Was the P0700 in the PCM or TCM?

Thank you for getting back on this.

The P0700 code came up when I used the ignition switch method of looking at the codes and then again when I borrow a code reader.

How hard is it to replace the solenoid pack and does it involve drain the transmission fluid please?

Thank you

Hi.

Please can someone help again. I have replaced both speed sensors and the solenoid pack, if anything the problem is worse.

If I accelerate hard from a standstill the car fails to engage a gear. It is fine if driven gently. Do the new solenoid and sensors need to be programmed or is there something else I should look at please?

I have seen a number of comments about ground issues with these cars could that be a problem? Would adding an extra ground directly from the solenoid help?

Thank you
