Wrong ATF used.

[CB900SS]

I see this has been covered many times already on this site, but after reading for hours and searching I'm still unsure as to what to do.

My truck has the 42re (1995 ZJ 4.0), it has 190,000 and has been serviced regularly. It was and still is shifting fine, I unfortunately have just changed the filter and filled it with definitely the wrong fluid.

I believe it was Type F carquest dex/merc. I'm not sure exactly what the containers said, but it certainly wasn't ATF +4, or even dexron II.

So, what next? What fluid to buy? Just drop the pan and swap fluids? What about the fluid in the torque converter?

I drove the truck only a few miles since the fluid error. What sucks is I am stuck home now with two kids until 8pm... and I really wanted to head to the beach today.

If you want to do it yourself, disconnect the transmission lines at the trans cooler if you have one, or at the radiator if you don't have a cooler.

If the lines from the cooler are long enough, put a 5 gal. bucket under the truck and point the lines into it, tie them or have someone hold them so the fluid will go into the bucket.

If you don't have a cooler and had to disconnect the lines at the radiator, slide a 2' piece of fuel line over the end of the each line, and run those into the bucket.

Start the engine and it will begin pumping the trans fluid out. Once it's pumped out a gallon or so, start pouring the right trans fluid in through the dipstick. Continue this until you used a case of trans fluid. Shut it off, reconnect the trans lines, start it, recheck the trans fluid level, topoff if necessary, or if it overfilled, drain some.

Or you could take it to a Jiffy Lube type of place and they can do the same thing, but it'll cost around $80 - $100.

Oh, and as far as what type of fluid, ATF +4 is the better one to use, but if the dipstick says Dexron II, you could use that too.
