When my EA is fairly cold and I make a right hander in 1st gear when it goes to change it goes into neutral, and wont change back for 10 seconds sometimes. Any ideas? It's a 1990 CPI 4 speed auto sedan.
My first thought too.
another thing to look at, is the earth leads on the battery...ALL of them...one of these smaller ones also supplies the auto computer and it HATES dirty terminals.

Forgot that one. I actually ran an extra 6mm wire on mine from the ECU through to the battery. I know it shouldn't have needed it (etc, etc), but it made a difference to the driving all round. But, mainly when the car was at operating temp, NOT cold. (Resistance increases with temp....)
I had an EF with a leaky extension housing seal, I knew it was time to top up the oil if it neutralised on the first right-hander on the way to work.

Reason: BAD typo...!!
Yeah, I done voltage drop checks, resistance checks, etc, but it was an "intermittent" problem (hate them ones!!). Eventually I got the sh#ts and done the "wrong thing" and ran another wire. Made the shifts so much more consistent.
This is not really an intermittant problem, it's pretty much like clockwork, so I'm a bit doubtful about earth leads since I cleaned/polished all the terminals on them when I gave the car a service a year ago. But I'll check them again to be on the safe side. Regarding the automatic fluid I think it's right on full but I'll check again. It really sounds mechanical and not electrical because it only does it when it's cold, but I'll check all the connections.
tommo74 you sound like you've seen it before, what could cause an inhibitor switch to do this on a cold motor on a fairly sharp right hand turn? Maybe it will do it with a sharp left hand turn, I don't make that many of them..
I think you will find its not necessarily just sharp right turns but more like when the box is under extra load. My bet is sharp left turns and steep inclines would have the same effect. At least thats what my girlfriends ute does!
