Transmission issues

Paidai1999

I have a 1999 Dakota slt with overdrive the transmission it was rebuilt 816 miles ago. When I start off first thing the rpm has to come to 2500 before shifting into 2nd, then it works normally after that. If the truck is turned off for approx 20 seconds I have to bring the rpm up to 2500 again. It was taken back to the shop and they told me they changed the valve body and solenoids and no change, he said it was a electrical issue but not sure. Has anyone ever had the same issue?

It's the shop's job to fix it and back up their work. If it needs further diagnosis, that's fair--it could be related to something they did not replace--- and if they don't know how to diagnose it, they should refer the truck to someone who does know how. The solenoids can easily be checked with an ohm meter. Was the filter serviced? Sounds like some kind of internal pressure issue.
