2001 LC Transmission drain and fill

[chudly]

Is the drain and fill on the 4 speed 100 series just a simple drain from the bottom of the pan and then fill through the dipstick and check while out?

With the search I keep finding information on the 5speed or the new WS transmissions.

thanks

Yep, pretty easy when you have the dipstick. Pulling the lines at the cooler and doing a full swap isn't bad either.

Yes, with the A343F just drain the pan, use a new crush washer to seal the drain bolt and refill through the dipstick tube. Check your final level with the engine and trans up to running temperature (trans in park/neutral).

The drain bolt tends to get stripped out, I don't think there is very much meat to the threads in the drain hole. I would use a new drain bolt every time, and be as gentle as you can when torquing it up. I'd use the minimum torque in the spec. Other than that, the job is dead simple.

Only a portion of the fluid is in the pan. Some people flush the whole thing, but that is a pain in the ass, I am just going to change what is in the pan for the next 3-4 oil changes. In my case that may be overkill, the fluid that came out looked brand-new. I bought a new screen strainer, but decided not to change it because the one already in was flawlessly clean. In other words, if your fluid looks good too, I wouldn't bother dropping the pan and changing the filter.

my fluid actually looked bright red on the dipstick. But it's good to know. I didn't have a funnel small enough for the dipstick so I didn't get around to changing it yet.

Here is a tip for you if you're new at this, it takes time for all of the trans fluid to drain off the walls of the dipstick tube.
Example, you add trans fluid, check the level, it says overfull, let it sit a good 10-15 min before checking again, the dipstick reading will change.
After your done and satisfied the trans is full, check it again after driving it for a day and letting it sit overnight.
Brand new trans fluid is hard to see on the dipstick, use a shop towel to contrast the dipstick.
