Vehicle speed

[quote:c67534b01b="javila"]1997 Dodge Grand Caravan 3.0 L automatic 2 wheel
with 77000 miles: I have recently replaced the transmission in this van. As soon as I started driving it again it has given me more trouble it gave me 2 trouble codes P0500 and P0740 and the speedometer does not work in drive but does work in reverse. I have replaced the vehicle speed sensor located in the tranmission. No luck speedometer still does work the transmission is shifting but once in a while when taking off the van does not want to accerate even when my foot is to the floor. When this happen it has a lack time of at least a minute or less to accerrate but the transmission is shifting. I have had various diagnostic testing and the same codes keep coming up. Any suggestions[/quote:c67534b01b]

Try disconnecting the torque converter clutch solenoid at tranny and see what happens.

No change speedometer still not working

Now we go to the coolant temperature for lock-up and throttle position sensor for throttle pressure, could have another VSS on the dash ( combination meter ) that the computer is not receiving the proper signal.

Fluid and filter change?

You might want to have it pressure tested-to ID internal problems.
