I have a '99 S70 T5 with a 5 speed manual transmission. I have never much cared for the abrupt engagement of the factory clutch, and I was wondering what alternatives are out there. Anybody have any experience with aftermarket clutches for these trannies?

From TME's website..
HIGH PERFORMANCE CLUTCH UPGRADE
High performance clutch kit (Sachs) for cars with dual-mass flywheel (1998 and later) with approx. 40% higher torque capacity. May require a different flywheel for some models.
hmmm...
Dunno if the feel of the clutch would be better, but I suppose you could look into it. I know I would have if that was around back when I did my clutch job.
New website, new products, limited info.

Last weekend I drove the snot out of my car, for the whole weekend, clutch engagment is very smooth now. Probably screwed up the hydrolics or something haha. I am not sure of any "upgrades" there are for the clutch. There may be some odd ball source around somewhere. Johann from vvspy is working on an ex-police 850, and his original clutch wasn't strong enough, but he replaced it with an R clutch (850 vintage). That surprises me because I would think that if there was a better alternative he would have done it. Especially for that powerhouse he's working on.

DG,
Are you saying that your clutch engagement WASN'T particularly smooth in the past? I'm just trying to determine if I'm the only one who feels this way about the S70 clutch.

Sorry, I keep getting errors when trying to post a message. I had typed out a long message the first two times, but I'll keep it short this time. The clutch was a bit harder than I thought it should be to engage smoothly, but in 1st gear only. Now, it seems much easier than I remember. I had a new clutch put in at 50k becuase of various issues (noisy bearing, worn out springs, etc) It still functioned alright though when it was in that condition. Ray N has the noisy clutch too I believe. Is yours hard to engage smoothly in just 1st , or is it harin in all gears? There was a TSB or something related to replacing the clutch and updated(?) parts to use. I don't exactly remeber and NHTSA just made their site harder to use and more useless at the same time.

My problem is tolerable during first gear take-offs, but "tolerable" was a carefully chosen word. Even worse is the occasional lazy shift into second, when I'm just puttering around town nice and casually. Given a chance, the engine will rev down too fast, mismatching the engine and tranny speeds, and causing an engine stumble as I let off the clutch pedal. It's rare, but darned annoying when it happens.
As for that service bulletin that you're referring to, it only applies to the '98 model year 70-series cars. Here's a portion of the TSB as it's listed in All-Data, which generally reprints the Volvo TSBs word-for-word:
-----------------------------
S70/V70/C70
MY 1998 (partial)
Campaign No. 92 Clutch control cylinder
Background:
Some vehicles may experience a decrease in clutch efficiency, which could result in difficulty when changing gears. To prevent this condition, a coupling on the clutch control cylinder will be secured.
-----------------------------
The TSB also lists a part number, 9181729, described as a "clutch control cylinder adapter kit 1 (contains quick coupling, seal and assembly fluid)."
I'm also aware that, beginning with the '99 model year, the clutch release bearing and slave cylinder were combined into one unit, which can only be replaced by pulling the tranny. (Yes, really.) That's why the aforementioned TSB doesn't relate to my car.

For 98's there is also a TSB to replace the clutch pedal
spring. This is to make it easier to engage. I've never done
that myself so I can't comment on how well it works. The
revised spring might have been placed in production on 99's.
If you have alldata subscription you could check on that as
one possible improvement. The TSB is titled
"Clutch Pedal - Revised Auxiliary Spring" and is dated July 1999.
TSB number is 4410004.
Described as:
>This Service Bulletin describes how to replace the existing, linear auxiliary >spring with a progressive auxiliary spring.
>This spring will provide smoother engagement of the clutch
I dount this applies to your 99, but thought I'd mention it.
And yep, my throw-out bearing (98 T5M) squeels about 30% of the
time in first gear starts and sometimes I can even hear it on 2nd
and 3rd gear shifts.

A while back, before my beloved '98 S70 T5 was totaled, I managed to get the throwout bearing replaced UNDER WARRANTY! It was making a fun little rattling noise which the first dealer tried to pass off as noisy lifters. I took it to another dealer in the area, immediately was told it was a throwout bearing. They even offered to put in a new clutch for the price of parts only (300 dollars) as they had to drop the tranny to replace the bearing anyways. What this adds, I'm not exactly sure, but if your cars are under warranty it's worth a try?
Good Luck!

I've done that clutch pedal spring modification. I found out about it when I had an All-Data subscription for the '98 model year S70, before All-Data had anything for my '99 vehicle. The TSB is not listed in the '99 model's All-Data database.
When I went to my local dealer with that TSB, they told me that they couldn't find it in the VADIS system. After I told them that it's listed for the '98 S70 and they found the TSB, I was able to convince them to perform this modification to my 99 model. (They had to call Volvo NA to get permission.) Even after I *gave them* the Volvo part number that was listed in the TSB, they managed to order the wrong part. When I showed up for the warranty service, they lied to me and said that the spring wouldn't fit my car. When we realized that they ordered the wrong part number, I asked them to order the correct one and perform the modification under warranty as they had initially agreed to. They said they couldn't cover it under warranty, but that I could pay to have the service done. Have I ever mentioned how much I hate Red Bank (NJ) Volvo's service department???
Regardless, the new spring looks like a little baby progressive suspension spring, not having the equally wound coils of the original spring. The cost was cheap, under $10 as I recall, and installation took less than 15 minutes.
The resulting pedal feel was "different," but not necessarily an improvement. It certainly had no effect on the disc-engagement problem that started this whole thread.
Bottom line: don't bother.

Sorry!
I failed to take note of the fact that you have a 99. What you were saying about miss-matching the revs and gear... On mine the engine doesn't seem to rev down fast enough at a higher rpm (say 3-4k shifting outta 1st)However if i shift at low rpm in first the revs drop way too fast. Like you said. So.. I dunno...
