Woe is me, and thrice woe!

V70 Ph1 Classic Auto in for MOT today. 1 advisry - rear tyre low tread so get 2 new rears put on. Thats all that needed doing. I asked my garage man to replace front discs and pads, which he duly did BUT BUT also asked him to 'gibbons' the auto box !!!!!!!!!!!!! Previous day got 16L of Volvo ATF (the real deal) plus O rings - £240 the lot - gulp!

Garage man did the 'gibbons' on the autobox - no worries even had almost 4L of ATF left over ..................... BUT now the box is misbehaving. I think it is what you guys refer to as flaring in 2nd gear ie almost b****y impossible to engage as she revs her heart out but eventually engages and off we go with nice smooth gear changes - much better than before. However having only gone 1 mile the Uparrow auto box light is lit and the EML also. return to garage and he reads the codes as 0100 control module faulty signal (from Autobox ECU) and P1618 and P1670 from Engine ECU. Resets the coeds and away I go off home - lo and behold both lights are on again after 4/5 miles and I think its in LIMP mode. My generic code reader shows P0785 (Shift timing solenoid???) and the reader is able to erase the codes and both lights are now extinguished. Suppose I should take it for a spin and see when they come back.
Can anyone shed any light on whether my autobox is fubarred or whether some electrical connection is maybe dicky??

Have you checked the fluid level, engine running & in park?

Good point. No was assuming my garage man had done all that and have no reason to doubt him but I'll go and check it. Just been on another run and got both lights up again by stopping and engaging the W button (assuming this starts in 2nd gear) and got a big clunk and both lights back on. Code was 0811 but erased it and off she goes but still with 2nd gear 'flare'.

Like Chris said, get the car up to temperature then with the engine running move go through the gears one at a time giving them 5 seconds each finnishing in park and then check the fluid level. The dipstick has a hot and cold side.

Sounds fluid based issue to me, or some residue has been dislodged and has messed up a shift solenoid.

Alas, this box has internal solenoids as opposed to an external valve pack, so if this cannot be restored by fluid change (maybe another flush needed sorry to say) and CORRECT level filling then the case has to come apart. Which means box out

I am inclined to agree with the above and since I know 9 tenths of
FA about the internals of my autobox I have decided to limp to Mackies in Glasgow on Tuesday for them to assess it and then I'll decide what to do with it. Obviously if its TOO expensive then that will be it but if I can sort it for less than £1500 I'll be relatively happy
