Default At oil temp light flash

So I just had an engine swap done and now my at oil temp light is flashing. It's an auto trans 2003 wrx. What would be the cause for this? How do you fix it?

It could be the throttle position sensor. Everything is all speculation at this point. I would download a program called FREESSM and get a Vagcom OD2 cable and read the codes.

I read the cars manual and it said when the light is flashing the automatic transmission control system is not working properly. I'm bringing it back to the shop that did the swap Monday but I miss my car terribly it took a month to do the swap

I blew my motor and swapped in a used one. Same ej205 I believe. Sorry if I'm incorrect.

Pull the code. Could be overheated, overfilled, bad sensor, etc.

How does it drive? Does it drive normal?
How many miles on the transmission?
Do you feel torque bind? You will really feel this when you are going slow while making a sharp turn, the transmission will be fighting with itself (the car does not want to move without giving it more throttle than usual). You may also feel a lurch when you stop and turn off the car.

What causes this torque bind? And how can you fix it?

A bad duty c solenoid can do it, as well as a bad clutch pack. It could even be a bad electrical connection.
Start with all the elect. connections first. You can also try replacing the fluid which occasionally helps with a sticky clutch pack.
If those don't help then I'm sorry to say its probably the Duty C solenoid.
Not the end of the world, but...

Look up: 4EAT,16 Flashes of Death, or Torque Bind Sucks, or How to Replace a Duty C Solenoid.

^^^That big mess is the title.

The flashing light does not necessarily mean an electrical problem only.

It may not be electrical, but it has to be something the TCU can detect.

I know the TCU can detect a short or open on the transfer duty solenoid circuit, I know it can detect a bad vss, I dont know the mechanism by which it can detect a bad clutch pack, unless it calls for 'lockup' but still detects wheelspin.

Ya i'm just going to take it into a shop soon. How much do you think these repairs will be? I know auto Trans repairs are expensive.

It could be not bad or a lot. Could even be a bad TCU.

I'd make sure they are familiar with the AWD part of subes.

Seems like 2002-2004 WRX's have planetary gear sets like the STI's. I'm betting its the Duty C Solenoid in the rear housing. However this is all speculation until you get the code read.
