If you didn't use dexron III Transmission Fluid, this may indicate the reason for the flashing light. Another reason is either too much or too little fluid.
My best advice is to take the car to a transmission specialist. Really, changing the transmission fluid in a Daewoo is not something that should be attempted by anyone but a specialist.
It for sure cannot hurt and may very well help. Have the fluid and filter changed, and see where you stand then.
Low Transmission fluid
If it started flashing after the water pump, it is possible that the timing belt/chain is installed improperly.
Depends if you have a manual or automatic. Manual transmission, no, there is no transmission computer. For an automatic transmission, the engine computer and transmission computer are one unit typically called an ECM, Engine control module. There are many different names for and ECM. Ford started using computer controlled transmissions in the early 90's and late 80's.
Older automatic transmissions had clutch "bands" that were adjustable when the transmission started to wear. Modern automatic transmissions do not have that option, but then, they tend to last a lot longer to make up for it.
The first fully automatic transmission was introduced by Oldsmobile in their 1939 model year. It was called the Hydra-matic.

To prevent the engine from being started while the transmission is any gear other than park or neutral.
if it is not going into gear when it is started, if it is a standard transmission then it could be that your clutch is not engaging or that your gears are stripped in the caseing of the transmission, if it is an automatic then your torque converter could be bad or there is something wrong with the shift linkage
Timing belt. Started from 2006, Honda changed to timing chain.
I just got home from the shop with the same problem, I was told that it has to be changed and its a dealer part only. Running an average of $475 just for the part. My check engine light came on and then the o/d light started flashing. To change it they have to drop the Transmission pan.
if it's a standard shift it takes 85w90 gear oil, i don't remember when vw started using automatics, if it is automatic it takes dexron transmission fluid. Youcan't get type a anymore, dexron will work just fine.
