What was the reason for "washing" the radiator?

The chances of fixing a leaking radiator permanently are very minimal. You should have simply changed the radiator altogether.

My recommendations;
Replace radiator
Replace the 2 transmission coolant hoses
Replace the transmission (gearbox)

Any other alternative will only end costing more money eventually + frustration.

Oh, and lastly..sack your mecho!

Let me be frank with you.

Your precious car gear maybe gone. And the cost of replacement will be about 500-700k.
Your mechanic is very wicked or incompetent. The gear maybe burnt due to lack of oil and wrong oil was used to top it.

Now scan and share codes here.

My advise to people here is that, always use professional mechanics to avoid pains at the end. Also, seek for advice before carrying out some repairs you are not familiar with

This is a real problem.

Op so sorry for yr predicament, but let me share my story with you.

In 2019, I had just bought a 2007 honda accord v6 with a perfectly working gear. I drove the car with my family all the way to warri from Lagos. On the way around sagamu, I noticed the D transmission light blinking. I stopped, checked for oil leakage or shorts, nothing. Checked and checked, nothing. I drove it to warri. By the next morning, it had cooked down, D light stopped blinking, drove within the town for abt 5days and returned to Lagos without any issues.

Within 3days after returning, on Eko Bridge, the gear suddenly stopped working. Long and short, gear oil was burnt, fibers burnt. Transmission toast. Had to get a replacement gear at oyingbo. That was where we discovered that the radiator hose that cooks the gear had been blocked causing over heating in the gear. Since I corrected it, I'm using same transmission till now, no issues at all. Shifts perfectly.

Your gear is not shifting perfectly, it's slow because it's not going to gear 1. So when you slow down, it takes time to pick.

You need a new transmission bro. But drain all the oil and replace with WS gear oil, and see if there's a difference.
