Good morning everyone,
So glad to finally actually be able to post I have been wanting to for months now.

My issue is a transmission problem and mainly I have owned the car wanting to restore t now for like 4 months and it was stolen for one of those and now I was not able to slip correctly into 4th and slowly it got worse to the point the transmission now makes that ehhhhhhh sound before it’s completely warm and then the N light comes
On and it won’t slip into third. It sometimes runs longer than normal and sometimes it won’t go from drive to reverse when cold for some time.
Yes I know I pushed my poor baby but so many mechanics let me down and I did my best to look after her but my concern is that the fluid isn’t black and it is only a little brown so could this just be that the *** that stole it put in the wrong fluid and it’s a computer fail-safe to
Stop damage?? I am convinced that if I was to put new SP-III and not flush it from the torque converter and change the filter it will start working again I have been told 100 different things with people trying to get top dollar or force me
For a rebuild. It has 230k on it but it was looked after really well and I have done a good job to restore it with what I can find from parts and so on and just bad luck.

I need to have her fixed by the 11th for work or I lose my job and or I will have to scrap her 😢 and refund the ctp and rego ASAP to get the refund to buy a shit car and hope not a Subaru XD so I don’t lose my job.

Please help!!
