just a quick transmission fluid question

[john99gtp]

I searched, but could not find answers to this specific question.

 

I read that the TGP tranny was designed for Dexron II, but you can use Dexron III. Thats sweet, since Ive already got a shitload of Dexron III laying around from when my GTP had the tranny problems. So thats cool.

 

My question is, I was planning on doing a pan drop on the tgp. Is it ok to mix the dexron II and the dexron III? Or should I really try and hunt down Dexron II? I dont want to do a flush in it, so thats out of the question. But if its safe to mix Dexron II and Dexron III, that would make it so much easier

 

 

Thanks

 

John

Dextron III/Mercon is compatable with Dextron II - Dex-III is just the updated version - you will be safe mixing the two.

Dave's right. They don't make Dexron-II anymore.

Dave's right. They don't make Dexron-II anymore.

I tried to find it for my old metro.

Now they make Dexron IV.

 

I remember the day that came out. Is it available yet and what are the advantages of running it?

Our dealership has it, as it has come in all 2006 GM vechiles.......I don't think its on the selves of part stores yet.

 

You can use IV in the III trans, but no III ina IV trans.

 

Its basically the same thing with better heat resistant properties.....which helps the fluid out in other areas.

Has anybody ever had a 100% tranny flush done? I thought I had heard one time that that is actually bad for the tranny because it weakens seals or something. I actually just did my first tranny flush and filter on my '98 Lumina and that was some black fluid. My cousin told me he changed it before it sold it to me. I only worried about all the black fluid that was still in the torque converter.

on an old tranny, it is bad to flush for some reason or another....cant exactly remember

 

 

old as in 120,000+ i believe

I had my Regal fluid flushed @ 128k. Didn't notice any difference afterwards.

I've heard you're not supposed to do it if your clutches are about gone... If your clutches are about gone, the old fluid that has broken down some is helping the frictionplates stick together... If you change it then, it'll let those trashed plates slip with the slicker new fluid... Much like changing the oil in a motorcycle that has a clutch that's about to go... it will immediately start slipping near redline...
