I have a 2000 3.2 tl with 149k miles. The transmission slips I have read that the 3x drain and refill can help. Where can I find precise directions for this.

 

Well, unfortunately if it is already slipping it's probably too late. A fluid change may help for a little while but will probably just delay the inevitable. How does the current fluid look and smell? If it is burnt and real dark then I probably wouldn't bother spending money on a case of fluid. You should also change the filter if you are going to change the fluid.
anyways, if you do go with it, there are a lot of threads explaining the procedure but it is pretty simple. Just do a drain, refill with ~3 quarts, and then drive around for at least a few miles while shifting thru all the gears. Then repeat a couple more times. You can also do the first drain and fill and then drive a couple hundred miles and then repeat two more times but since yours is slipping I would just do the drain and fills in quick succession.

 

Its as simple as it sounds... Drain and Fill (3 quarts) by 3 Times.
The gap between changes should be at least 100 miles or 1 week to let the new fluid dilute with the old one.

 

interesting, never thought of doing it this way, i did a 3X2 with castrol tranny fluid about 7k ago, my trans is shifting great, but i still want to do a 3X3 with oem honda fluid. Or maybe i should leave it along since its shifting great, btw, previous owner had trans fluid replaced about 4k miles before i bought the car, so the trans has been maintained.

 

^ I would stay with OEM Fluid, Honda and Acura trans are very picky with their Trans Fluid and you should avoid using Aftermarket Universal ATF on them.
There is a nice package of 12quarts of DW-1 on amazon at a great price, Those are enough for 4 drain and fills.

 

OEM or bust !

 

I'm new here I'm Keith I just got my TL 04 about 6 months ago it runs super strong and shifted great until the other day it felt like it started to slip and it shot the rpms up so I let off and it started pulling normal I drove home and haven't driven since I checked fluid it's kinda dark but doesn't smell too bad I'm gonna try the drain and fill and filter if that doesn't work what accord
trans or other Honda option do I have for a trans thanks for any help

 

06-07 (non-hybrid) Accord V6 automatic transmission is the best alternative.
Make sure to check ATF level with the car at operating temp., on a level surface, right after shutting off the engine.
The fluid level should fall between the upper & lower marks on the ATF dip stick.
