2002 PT auto trans problem

Hi, this really depends on its service history.

The following are the recommended service intervals on the Merc S500:

Note: operate A/C at least once per week, to maintain lubrication.

Underhood & Undervehicle

Every 3,000 miles - Replace engine oil & oil filter. Clean battery terminals. Adjust drive belt. Check power steering fluid. Check steering & CV BOOTS for wear and replace if necessary. Lubricate front end suspension.

Every 6,000 miles - Check transmission fluid condition and level. Check brake pads and caliper components - replace if necessary. Lubricate driveshaft U-joints. Rotate tires. Lubricate wiper arm linkage and pivots.

Every 12,000 miles - Adjust engine valve clearance. Replace distributor cap & rotor. Drain and replace engine Coolant. Replace Air Filter element. Replace Fuel Filter. Replace wiper blades.

Every 24,000 miles - Replace Drive Belt. Replace A/C Compressor Drive Belt. ** Change auto transmission fluid & trans filter (this is critical and must be adhered to) - preferrably do a trans flush at same time. Replace drive AXLE fluid.

Every 36,000 miles - Replace HT leads.

Every 2 years - Replace brake fluid (also clutch fluid if applicable). Replace power steering fluid.


** If you intend to keep this vehicle long term, then consider changing the trans fluid & filter every 20,000 miles. This is the secret to automatic transmission longevity.

needs new tranny my truck did the same

well, it would be to your advantage to change fluid and tranny filter. before it is to late. change fluid and filter every 45 to 60 thousand miles. for a better working tranny. have a good day !!

fuel filter, air filter, tran fluid filter and change.( if its an auto) transfer case drain and refill, plugs and wires, coolant system drain and refill, thermostat, they claim timing chain/belt, but thats an awful lot of work to get into that.. how long has it been sinse you changed brake pads, rotors, and drums? may want to consider that..hope this kinda gives you a good idea

If you don't have synthetic in it now I woundn't, because you can not get all the fluid out with a regular transmission fluid change. Your transmission holds 14 to 15 quarts and when they do a fluid and filter change they replace about 5 quarts from the system.

the 2nd & 3rd gear solenoid needs replacing. It is mounted by the trans filter inside the trans pan

You allways check the transmission fluid level in car after the car has a few minutes to worm up. If you have not had the transmission fluid and filter change in a long time then you need to do it. The fluid and filter should be changed every 30,000 miles to keep you from having problems. Hope this will help you.

In all probability, the transmission fluid has stopped doing its work. You should have changed ATF fluid and filter about 60k miles ago. Auto transmission on 1998-2002 Accords are notoriously weak. ( i own one). I would venture to say that you have abused the tranny beyond its possibilities. If D light is flashing, transmission computer has detected a problem. Change tranny oil and filter to see if you can save it but outlook is not good.

Service trans every 2 years or 24,000 miles.Buy a trans filter kit,remove trans oil pan,replace or clean filter(some tranys has a wire mesh screen in them that is cleaned,not replaced),replace oil pan & refill with recommended amount & proper type of fluid.REMEMBER THIS:CLEANLINESS IS GODLINESS WHEN WORKING ON AUTO TRANS,DON'T LEAVE ANY PIECES OF RAGS OR ANY OTHER MATERIAL INSIDE OF TRANS!!!

The fluid boiling over is caused by the slippage heating up the fluid, your clutch pack is worn out, you will need an overhaul.
