Transmission fluid change

[cj80cruiser]

I read the step by step instrutions on how to drop the pan, change the filter, reseal the pan, and then flush the transmission but I don't want to go that far. I'm just looking to drain about 4 quarts by removing the trasmission cooler return line and pumping 1 quart out at a time until I have removed the 4 quarts.

Has anyone done it this way before? I've heard not to flush an older tranny.

What brand ATF would you get if not getting OEM...I'm looking at semi-synthetic Lucas ATF. I guess that would be fine to mix with my old ATF?

If you just want to replace 4 quarts, remove the transmission pan drain plug, drain (approximately 4 quarts will come out if on a level surface), put the plug back in, refill through transmission dipstick.

X2, measure what drains out, and you'll have a real good idea what needs to go back in. Do a few of these over the next few months and you're good to go.

I've only used Amsoil ATF. No problems mixing with the Toyota ATF.

I guess maybe that would be easier.

I used to use Amsoil but it's so expensive. Anyone using Lucas?

I want to say Singtoe is; maybe he will confirm if he isn't elbow deep in a V8 swap.

Try Castrol IMV if you want a good ATF under $5 a quart. Amsoil is good stuff I hear.

It seems all fluids have sky rocketed in price lately. I guess the oil companies figured that if folks aren't buying as much gas, then they have to make up the fiscal difference somewhere to keep their shareholders happy and fat.

Amsoil is probably the best but I would actually change it not just add a few quarts.
You can actually pump the majority of your ATF out using the same method, or you can take it to a T-Tech machine which supposedly just uses your ATF pump to replace probably 90% of the ATF. So it doesn't "flush" or use any chemicals it just pushes out the old and pushes in the new ATF using your ATF pump under the same pressure your trans is always under.

Also if you use Amsoil you can let it go 100K so wont cost any more in the long run really.

Here is some info on the T-Tech, never used it so don't really know but if what they say is true then sounds like a good deal.
