My 02 Trans-Am has just run past the 40k mile mark, and I'm curious as to whether there is any special maintenance I should be looking at doing to it in the near future. The car is bone stock, and here's a list of service type stuff I've done to it in the past year and a half or so


Summer 2005, 22k miles
- Replaced pads and rotors (OEMs were warped)
- Replaced transmission and differential fluid with Redline synthetics
- Flushed and filled coolant

-Spark plugs replaced with NGK-TR55s at 24k miles

Oil has been changed about every 5k miles with synthetic since I've owned it (bought it with 8k miles on it), and air filter is changed about every 12k miles or so.

Here's a quick list of things I thought I may need to do soon, I'm sure there's more, so let me know what you think.

- Replace belt
- Fuel filter (last replaced at 15k miles I think, it's been a while)
- Flush and refill brake fluid
- Timing chain? Not sure how often these need to be checked or replaced.

Thanks guys.

I don't recomend synthetic fluid in an automatic tranny because they were designed with certain friction properties in mind. Plus, ATF is an oil which will not harm the clutches. The rear end is a different case.

Other than that you have been pretty damn protective of it so I don't think you will have any problems.

I suppose I should've mentioned my car's a 6 speed.

I would say the timing chain and the brake fluid replacements are a waste of time and $. Hit it with some seafoam and run it! Your usual maintenance schedule is still adequate.

Your lucky, then. You can fix a manual in your garage easier. Need less special tools.

my exact thoughts (other than the seafoam)

You shouldn't see a normal timing chain failure until over 80K. I have never had one under that number. Knock on wood.

what happens when our timming chains go. are ls1's like other engine (non interference)

I'm curious about this too, which is why I asked whether or not I should look into checking it. I'd rather replace it long before the chain breaks if it'll take my motor along with it when it does.

Loss of power and hard to start.

Timing chains will pretty much last forever if you keep up with changing the oil on a regular basis. People who run old oil will be more prone to breaking there timing chain because old broken down oil will cause more heat on the chain and more friction which will cause it to stretch or break. In another case a highly modded car with lots of torque can easily break a timing chain over time as well. Thats why its best when you hit the 400 hp mark to put a double roller on or thats what I have always heard.

Yeah my car has over 154k miles and its still on the stock timing chain but the engine is stock too.

Timing chains are designed to last forever
