A transmission flush is in order for sure, if you have 25K on the engine you can flush the transmission. The rule of thumb is if the fluid is brown flush the transmission.

[pfeener]

Just to make you feel better. I had just over 100K on my 98 S70 before I flushed it for the first time (didn't know any better). The flush did wonders; smoothed out the shifts and the torque converter lockup.

[Bay13]

I've heard lots of stuff on the various boards about not flushing after x amount of miles. Just know that a transmission flush donesn't fix your car if it has a problem, so the same applies in reverse, it's not going to break it by putting new fluid in. Most that flush find the shifting pattern becomes smoother.

buy the IPD flush kit if you want to, and that has really good instructions...I forget what the ID of the hose is, you could just go to home depot and buy that, get a clip/oring from the dealer, and I could scan the IPD instructions for you....

EDIT: actually, the IPD instructions are on their site.... www.ipdusa.com

We bought our 95 960 with 109K on the clock and flushed it for it's first time. The fluid liiked like chocolate syrup when it came out and the car now has 152K and it shifts perfectly.

Hi guys I am very familiar with all that is involved in flushing the transmission as per Ipd's and Rich's instructions and I will be ordering the flush kit from IPD becuase the clip and O ring alone at my dealer are 10 bucks. So before I begin I have 2 questions: my Mom's friend told me I should ask about a torque converter drain plug so...

1) Do we have a torque converter drain plug on our car's and do I need to worry about not getting all of the oil out of the torque converter? I am almost postitve that I need not worry about this and the flushing procedure takes care of all of this but I wanted to confirm.

2) Also can anyone describe to me what the lower hose looks like that Rich describes in Bay 13? Since the top one is the return line I assume that the bottom is the IN line to the tranny, so it would look the same as the top line but on the bottom...duh right?

Oh, and since MY S70 is a '98 does it HAVE an external transmission oil cooler? From what I have read it sounds as though I do (since Rich installed one on his 850 from and S70) but I am a bit confused.

So thanks for all the help in advance guys I know I asked a lot but I searched and these questions I don't think were answered definitively and I want to get this right the first time (without starting a thread about it ).

Thanks/

Brad

The bottom hose does go to the trans from the cooler in the radiator. You do not have the extra external oil cooler, that is an option/addition. The bottom hose is much harder to get off than the top, most people use the top hose, just disconnet it from the radiator and put a clear hose over the connector and then route it to what ever you are going to collect the old fluid in. There is no torque converter drain plug and one is not needed your are running the engine to flush the fluid out of the transmission, this will include the torque converter.

I plan to flush my transmission soon. I don't want to buy the buy the IPD flush kit. Does anyone know the internal diameter of the hose?

[TRACStar]

I cut a section of garden hose and used a small pipe clamp on the fitting on the return line. worked fine for me but you can't see the fluid going through and you end up wasting a half a quart of new fluid

10mm if I'm not mistaken...could be wrong....

I bought 1/2" ID tubing. Worked great. It was a litle tight, but better tight than falling off and shooting tranny fluid all over the place.

I will measure the ID of the hose for you when I get it. The oring and clip alone at my dealer are like 10 bucks ( got to be the most expensive place around) so I just figured I might as well order it from IPD because it is on sale right now anyway for $12.95 or something. I'll post back.

Thank you Rich for clearing that stuff up for me about the torque converter, but I figured I'd check just so I could say that I did. I think I am just going to try and drain from the bottom hose becuase since I have owned the car ~25k it hasn't been changed, and who knows how long before that. Thanks, Brad

I didn't order it from IPD because my debit card has expired. Do you remember how much shipping was? It won't tell me until I put in my nonfunctional card number.

I've got to get to the bank today. Hopefully I'll be able to leave work while they are still open.

Thanks for the information on the ID of the hose. The cut garden hose sounds good. My neighbor just happens to have a hose, <evil laugh>..

What kind of odds will you give me on being able to reuse my oring and clip? Worst case scenerio I can drive my other car to the pick up the new, overpriced pieces from the stealership.

I wouldn't worry about taking off the bottom hose. It is not like once you hook everything back up that the fluid in the cooler is going to stay together. It's going to dilute itself with the other fluid. Or, maybe I'm just not dedicated enough.

By flushing the system according to the instructions using the top hose, you also flush the fluid in the cooler.
