Hello,
I recently purchased a used honda prelude se with 170,000km on original h22a vtec dohc engine. From a private seller.
The car runs great and there doesn't seem to be any major issues except he told me he drove it "wrong" for almost 20-40 km until he realised what he was doing.


My car has the sportshift option and apparently he put the car in d4 (thinking it was drive) and drove car this way. He didn't change gears and said he thought the "1" indicator on the screen was a defect.


He said he only drove it 20-40 km this way by driving the car 50-65 max on residential and business streets. He said he didn't here anything break except the cars engine "rumbles" a bit when it idles.


This car has not given me any problems and the transmission still shifts smoothly.. but this worries me as I do not want the engine to go out or transmission to fail. Is there any safety measures I can act upon such as replacing atf or avoid using ss for awhile?


A few issues that came up with car that might be related is as follows:
The car may have a slight leak near the oil pan gasket/ front seal, either this is making the oil go low very fast, or the fact that the engine was at such a high rpm usage for a while that the engine needs more oil consumption?
The oil pressure indicator starts to slowly fade on when my car has come to a stop, but then goes away immediately after pressing the gas.
There is a slight clicking noise coming from the drivers side wheel/engine. Not sure if its from wheel or engine, only can hear it when car is driving
He told me car never went to red line, and when it was in d4 (1st gear) the rpm went as high as 5000-6000rpm but never red line.
He told me he never had problems with the car. So I'm hoping this is the case, I recently flushed the engine and replaced oil/filter.


If you can help me out with:
Possible issues that may rise in the future with using ss incorrectly
Ways to prevent further transmission/engine damage, and how to "bring back to life" current transmission.




Thanks so much, and I appreciate the read. Hope to hear from you soon!

Here's what I would do:

. Change the ATF, after the transmission reaches normal operating temperatue. Most Hondas take around 3 quarts. I would go with a full-synthetic ATF that meets Honda's specifications. Mobil 1 Synthetic Multi-Vehicle ATF will likely fit the bill. This is about all you can do to preserve your transmission. It's a simple drain and refill procedure--no pan or filter to worry about. Change it every 25,000 miles.

. Change the oil and filter, using Mobil 1 5W-30 full-synthetic, every 6,0000 miles or 6 months, whichever comes first.

. Change the brake fluid, using Valvoline Brake Fluid.

. Partially change the power steering fluid, using Honda Power Steering Fluid.

. Check the driver's side half-axle and wheel bearing for damage.
