Grand Caravan Sport 98 3.8 lts Transmision Problem

[dcamus]

I have a Grand Caravan 98 sport 98, when the use of several kilometers turns on the check engine and makes no changes speeds, the engine shuts down and turn back to normal and make the appropriate changes. Codes that shows are as follows PI1776, PI1775, and PO700.

After switching off the engine, the day after the check engine goes off and works normally. The problem mainly makes road.

Already changed input and output sensors, and the problem persists.

Thanks

It sounds like a solenoid issue.

Try changing out the transmission fluid ... ATF3 or ATF4 only.

Ok, forget to say that I have already changed the transmission fluid to ATF3 recently and the problem persists.

I thought about changing the selenoides pack, but i dont know if this solves the problem.

I get this problem intermittently. Basically, sometimes it won't go into 4th gear.

Other than the solenoids, I'm not sure what it would be.
