From Car Wash To Transmission Problem. Help by stpat1(m): 7:42pm On Jun 20, 2016
Hello guys I need your help.

I recently got my car engine (Honda civic 2004 model) washed some few days back. After about 10 mins drive from the car wash, I noticed that the car was not changing gears even with continuous revving.

I stopped by my mechanic's workshop only to be told that my gear oil compartment has been flooded with water. We got it drained (It was actually flooded) and replaced the oil but the problem persists.

The mechanic is already suggesting I buy a new gear box. Is there any solution? As I am still optimistic that there might be some solution.

What do you suggest. Experts pls help me out.

I don't think I agree with your mechanics, how much water could possibly get into a transmission when it is being washed? Or was the vehicle soaked in water? Scan and check "TPS" if tps is not functioning car could be stuck in first gear for a long time

I once had a similar issue after an engine wash.
Water somehow found its way into the transmission socket and corroded some pins over time.
Result was transmission not able to move to the last gear.
So yes, scan vehicle and look in the above direction.

was the car washed outside or engine bay

lets assume that water got into the transmission draining once wont do the trick

if you are doing a transmission flush you flash twice or 3 times before final refill

in your case you said drain and refilled and you didnt mention how many times

if the wash was inside the engine bay then your need to check all connection wires to the gearbox blows them with compressed air and also use contact cleaner

Thanks. I only drained once. I will try and check all connections thoroughly and reflush again. I want to explore all solution means before concluding if the gear box will be changed.

I flushed the transmission oil again and also flushed the solenoid as attached. I think solenoid or changer. All in all, the problem still persists.

Next to do is to get someone to come do some diagnostics. I just hate the idea of changing the entire gear box. I will explore all other options as changing the gear box will be the last resort.

You have been advised by many responders here to scan your car. This, you have not done. Start from there!

Meanwhile, I dont understand how washing your engine bay would flood your transmission Did they try to wash the transmission internals too? Can you post a picture of the transmission oil 'compartment' that was flooded and drained?

Have one thing in mind - Honda solenoids don't like strange fluids. So 'flushing' them might effectively be RIP!
