haveing a problem w/Trans.

I have a 98 Dodge Grand Caravan. It started showing the check eng. light. So I had it scanned and came up with these 2 codes
P1788 - pressure control solenoid B open-circuit

P0700 - trans. control system malfunction

Is there anyone out there that could tell me how to fix this problem

Thank you in advance

:2cents: You might find something at www.Allpar.com. Sounds like a for sure electrical problem but, have you been using nothing but ATF-4 fluid. If not, have it flushed and refilled. Well.. at least you're back up to the top of the forum.

Hey Chico you may want to go read this link that was just posted a bit ago.

and It's ATF-3+ for tranny fluid right?

"and It's ATF-3+ for tranny fluid right?"

Well yes and no. Chrysler recently stated ATF-4 can now be used in ATF-3 applications. In fact, I think I read somewhere that Chrysler is no longer making ATF-3. Personnally, I've got doubts about the whole situation so I would stick with whatever fluid type your manual states. In that respect, yes you are correct - use ATF-3 in a 98.

i'll try flushing it and putting atn-3 in it and see what happens if there is no change i'll have to see about getting a new transmission

If you have the transmission completely flushed there should be no problem. I recently had the ATF-4 replaced with ATF-3 and no (new) problems...From what I have read, ATF-4 is only second best for our minivans and can cause a variety of problems. The cars are designed for ATF-3 and that is what I will continue to use.

Remove the negative battery terminal and let it set for a few hours. That erases the computer memory.
