So what would alyuh recommend under the conditions we cars have here in trini to change the filter
Here is the site
Comfort, ease, and security are provided by a smoothly shifting automatic transmission - one of the most complex, yet reliable components of today's passenger car.
But, because it is so reliable, it is out of sight and out of mind. Taken for granted. Neglected. Until something goes wrong.
Routine service and maintenance of the automotive transmission fluid and filter will ensure the reliability of this essential piece of equipment.
Fluid, under pressure, causes clutches to engage and disengage, valves to open and close, springs to load and unload, gears to change ratio and keep the torque converter in constant motion. The transmission fluid acts as both a lubricant and a coolant, and additives help combat oxidation and foaming while preventing the breakdown of rubber seals and gaskets.
To perform its function, transmission fluid must be free of harmful foreign particles, varnish and sludge. Eventually, even the best fluids need changing - normal wear and heat build up cause contamination and varnish accumulation.
The automatic transmission filter prolongs the life of the fluid and transmission by trapping foreign particles and abrasives from the fluid. But it, like the fluid, will eventually wear out - become plugged and will no longer be able to protect the transmission.
Purolator recommends that the transmission filter and fluid be changed at least every 12 months or 12,000 miles. Check the owner's manual to determine if a more frequent change is recommended.
Since automotive transmissions are so reliable, trouble shooting is an excellent way to determine if the filter and fluid may need changing. The following are signs that could indicate a filter and fluid change is overdue:
* The fluid has changed color from red to brown or yellow
* A change in smell that ranges from a sharp, pungent smell to a burned-rubber odor
* Rough shifting
* Varnish on the transmission dipstick
* New or unusual noises
* A clicking or buzzing sound that may be indicating fluid starvation due to low fluid level
