Ok,the thought of paying Jiffy lube a hundred bucks to service tranny just seems sort of dumb. I want the full drain and fill with flush. My question is, could it be done at home?

That is to say, could on pull the return and fill lines, place fill lines in bucket of AT fluid, please return line in empty bucket, turn on truck, watch empty bucket fill with old fluid, watch other bucket slowly empty? Then when same color fluid is coming into old bucket as is coming in....would you be done?

Ok, I admit, this is a crazy idea. Could it work? Do you need pressure involved? Would it burn up the pump? Thanks.

depending on the mileage your tranny has seen you might not want to flush it. if the fluid has never been flushed before and you have high miles over 100k its possible that you will flush it and the tranny may not even work anymore. sometimes the gunk in your tranny you are trying to get out is actually what is keeping your tranny working. might not be the case for your vehicle but i wanted to make you aware of that. and please dont take your vehicle to jiffy for that, i hate to constantly dog them but im sure your capable of draining & refilling your tranny. for a flush i would havta recommend the dealer.

 

Do a search on Jiffly Lube.. I wouldnt pay them to do ANYTHING...

read that link from Gadget and go from there.. If you have never overheated your tranny you should be fine with a flush... And for the best reuslts have it filled with AmsOil ATF, best on the market.. hands down...

 

The link to gadget's site pretty much explains it. But, in simple terms, the cooling circuit provides pressure on the outlet side, which pushes the fluid through the radiator cooler and back into the trans via the return line. If you break the lines, the return side doesn't have suction to pull the new fluid into the trans.

 

I have a question about doing mine. I bought both my vehicles at around 100k each. I do not know what maintenance the previous owners did. *offtopic* The Subaru(Auto) has about 135k on it now and I notice when its cold or I just start it up it won't shift into drive or accelerate when I hit the gas. It seems to take a while for the gear to engage. *offtopic* My 4Runner is at about 125k, I am doing a complete tune-up on it and part of that was going to do the transmission fluid. However, after reading posts it may not be worthwhile to do this. The only time I've seen my A/T light come on was during a spring time run and the whole trail was gummy mud. I had a bad radiator at that point and I haven't ever had the light come on again since I fixed it. So, should I flush these vehicles? *offtopic* and if not any recommendations on the Subaru, the runner is fine otherwise. *offtopic*
Thanks alot for any help.

 

If you had the light come on you need to have it checked... that toyota light comes on at a dangerous high number, i want to say around 300?? Your fluid is for sure toast, and hopefully thats it... I would check the fluid out or have a shop check it out, if its really really bad you may just end up running it till it dies.... read the info on gadgets site..

 

STAY AWAY FROM THEM

 

Sorry to revive an slightly old topic, but can you do this at home without one of the machines mentioned on gadget's site?

 

Yes you can. We've discussed the DIY method in quite a few threads on here. Here is a link to one thread with all the info you need.

 

i choose whether to flush or just drain and refill depending on the way the fluid looks and if its even recommended by the factory. if you think your fluid is really bad and you might ruin it by flushing than a safe bet could be to drain and fill, then drive and repeat this process a few time till the fluid looks clean enough to actually flush. if its worth it to bother. o ya dont forget to change that filter too
