No idea .. its a transmission error .. so my guess would be that a solenoid inside the gearbox is malfunctioning and needs replacing ??? Or possibly it is not getting the right voltage due to an external fault ???

May shed some light on ths issue but it looks like your going into the box to sort this one.
-
is it easy to sort out, as ive never worked on a autobox
-
I haven't a clue I'm afraid. I'd rather say that then tell you something wrong
-
What symptons, if any, are you experiencing
-

the first thing is the spanner light on and the car pulls off as though its in 3 or 4th gear had
the codes read and came up with p1700 and p0748
-
Selector lights working as they should?
-
Lets start again.
Which ECU is reporting these codes?

You really need to get a tech II on it is there a member local to you that has one or look fir theboy :y
the only way you will get definate answer ;D
-
if it is the gear box are they easy to change

OK, if its the snap-off one, I think that reads in the TCM codes as well and Engine ECU. So follow the diag procedure for the P0748 (Pressure Control Solenoid (snap-off doesn't read next part))

Hard to say without knowing exactly what fault is ;D

I meant one of these
Link removed as its an illegal clone of a commercial product
Its one you can use on your laptop cheapie version ;D
-
I have a personal theory about codes to do with gearbox and that is to change crank sensor before doing anything else - I was getting the P1700 a few years ago and crank sensor and ATF change seems to have fixed it.

Replacing solenoid?
-
yes had it done at agents
-
had the car back today from agents they said theres still a fault with the torque converter stuck off buts its intermittent ,they also found a few bits
of plastic which they seem to think is a thrust washer
are these 2 problems easy to sort out
thanks
-
Your be dropping the gearbox by the sounds of it. There's a good how to about the thrust washer on here some where. I always thought the torque lock up was mechanical with no electrical components. So not sure on the answer to that one.
