i am at the step for T-45 and it will not fit into transmission plug,.i tried t-40, it will not fit. i am trying to but t-35 but it is not manufactured bt any one in the world. HELP?please.I am aware that this thread is old, nonetheless this information may shed some light on performing maintenance on a fill for life transmission, and how to perform this procedure. I could not find a procedure outlining the steps to take however I have performed this procedure on all the automatic transmissions I have owned in the past (yet the all had a filler tube) and it has worked wonders.
This weekend, I just changed out over 10qts of transmission fluid from a 2007 Veracruz total capacity is 10.9 liters which equates to 11.5 qts (I believe)
1. Tools needed for fill plub torx-t55, drain check plug torx-t45, IR gun, funnel.
2. Fluid Valvoline Max Life synthetic fluid that meets the jw3309 spec from hyundai
3. Two bottles lubeguard red.
First one needs to remove the black air duct two black plastic screws connected to the top of the railing of the car. Once removed try to use the t55 torx to crack open the fill plug it is really tight.
Go underneath and remove the plastic cowel there are about 8 bolts.
Go back to the engine compartment. Looking down you will see two rubber coolant lines with clips holding them to the transmission cooler. Remove the the bottom coolant line and direct it straight down to where you removed the bottom engine cowel.
Direct the hose into a gallon jug that is marked to measure 4qts. Have an assistant start the vehicle with the emergency brake on and vehicle in park. Allow the jug to fill up to the half way mark, tell assistant to shut vehicle off. Pour in 4qts of Valvoline max life full synthetic tranny fluid using a funnel. Reason for over fill is NOT to allow the tranny to run dry.
Start vehicle again and and allow fluid to fill to the 4qt marking made on the gallon jug, shut car off. Get another jug marked the same way. Start vehicle and run until the fluid reaches measured 4qt marking. Stop vehicle and pour in another gallon of Valvoline maxlife full synthetic fluid.
At this point you should have drained 2 gallons of fluid and refilled transmission with two gallons of fluid.
Grab another jug with the 4qt marking, make another marking at the half way point. Start vehicle and fill to the half way mark and stop engine. Refill transmission to with another (half gallon only).
Raise vehicle in the air and on jack stands have assistant put car in drive and raise the vehicle to 55-60 mphs and run this for about five minutes, have them let of the gas and allow the mph to fall to zero and place the vehicle in park.
Use the IR gun and point it to the bottom of the transmission to take a reading then point the IR gun to the transmission pan and take a reading between the two readings you will need to get between this temperature range 120-140 degrees. If the reading is not there yet, repeat process of jacking car in the air and race engine to 50-60 mph to lock torque converter and heat the tranny fluid.
Drop the vehicle and have the assistant press on the brake and place the vehicle in R, N, D, and other gears pausing in between for 2 seconds, now have them reach to the Park again pausing for two seconds in between gears.
Us the IR gun take the temp readings, once these readings are between 120-140 degrees (preferably the lower allows time to check fluid level).
It is a must the vehicle needs to be running in park. Place a pan underneath and use the torx t45 to loosen bolt and remove this bolt, transmission fluid should flow at a steady stream or a drip (preferably at a slow drip), if no transmission fluid is coming out, put plug back in tighten and shut vehicle down. Add half a quart of transmission fluid and add the two bottles of lubegard red.
If you are at a slow drip then add two bottles of the lubeguard transmission protectant.
Your done. Hope this helps (oh by the way the original fluid from the veracruz was black for the first two gallons and became red on the the third gallon).
