Replaced Tranny fluid and then....

[littlejuanito]

I know I shouldn't have done this but I ended up doing a drain and re-fill tranny oil change about 2 months ago and now my transmission is slighlty slipping when cold.

My car has 165,000 miles and since I got the car 3 years ago at 90,000+ I had not replaced nor added any fluid to the transmission and never had any problem with it either.

I went and listen to this stupid mechanic who told me that the fluid was too dark and recommended I drain and re-fill ASAP....Now I regret it

Anyhow, what's done is done. I have added some of that Lucas Tranny fix and it seems to have fix the problem, but just slightly.

Does this mean my transmission gonna go bust in a few months or what?

What else ca I do?

how many times did you drain and fill? which fluid did you use?

when you did all of this did you replace the filter too?

[Rob21]

Fluid type would be very important here.

[RedGalant2k1]

Do a full transmission fluid flush, with filter, and with Mitsubishi Diamond SPIII trans fluid only.

[Corey2kG]

Isn't the filter internal?

[9G]

yup. 99s have external at least on the v6 ones.

[Corey2kG]

What about a 2000 v6? This will be good to know when I do mine.

[99galantES]

99 I4's have external oil filters as well

[Rach3T8G]

They're talking about tranny filters

[4g63lover]

some 2000 I4's have external oil filters idk about the V6.

[littlejuanito]

I know for a fact that the place I took the car to get serviced knew about using Mitsubishi Diamond SPIII and told me that that was what they were gonna use....Now if they really used the Mitsu kind I will never know...But yeah, as far as I know, Diamond SP was used...

It was only drained and filled once. And the car is a 2001 so I dont know about replacing the filter on my model

[Corey2kG]

How can I go about finding out if the 2k v6 has an external tranny filter?

if its not a mitsu dealer and you didnt bring your own trans fluid then i bet its not mitsu fluid.

also when you drain and fill, im not sure how much goes out but i think its somewhere only in the 50-60% that you change.

its right on top of the trans in the engine bay.

01 doesn't have tranny filter.

Bottom line, get it FLUSHED, never...ever, just to a drain and fill.

if you cant see it under the hood then you have an internal one.

[Corey2kG]

I don't even know what the tranny filter looks like haha. I'll call the dealer Monday n ask. I do know that they want $210 to do a tranny flush.
