2G Engine speed increases but vehicle speed doesn't increase

[VolcomDSM]

So I just got my car back from the Transmission shop for the third time and I yet again have another problem. A couple hours after getting my car back I have issues. First the engine wouldn't start with the clutch fully engaged. Took a couple tries for it to finally catch and turn the motor over. After driving it for a couple minutes I noticed the rpms acting up. It progressively got worst to the point I couldn't drive it. The RPM's would should up to about 4-5k but I wouldn't get any increase in my vehicle speed, then I started smelling a rotten, sewage smell coming from the car. After parking, I opened up the hood and it was extremely hot under the hood yet the engine was not overheating. leaning in closer the smell appeared to be coming from the Transmission?...I sent it to back to the Transmission shop but I'm worried they are going to try and say it's something else that wasn't caused by them cause the guy mentioned on the phone that my catalytic converter could be clogged up or my O2 sensor could be out....just seems like more than just a coincidence that it does this as soon as I get it back out the shop again.....any thoughts??

clutch is not fully engaging. this will destroy your syncros in the transmission. adjust your clutch pedal by backing out the master cyl rod. when you can depress the slave cyl using your finger then you have backed it out enough.

What up bro, why was it in the shop? that's smell is most likely you clutch disc slipping. If the car was in for a clutch install they might have forgotten to resurface the flywheel or they didn't resurface it correctly. This would explain why your rpms go up but the car doesn't speed up like it should. When a clutch is slipping you will get that awful burning rotten like smell.

sounds like something on the clutches part. how did the clutch disc look after the transmission was dropped? Were you able to put the transmission into every gear and rotate the input shaft by hand to make sure it spun nice and smooth? Is the shop handling the rebuild reputable or is recommend sending it to a place like TMZ for a rebuild since they are familiar with our transmissions and are trustworthy.

It was in the shop cause my clutch burned out on me about a month ago. I'm not comfortable with Transmissions so I sent to a Transmission shop. They replaced the clutch assembly, resurfaced the flywheel as well as replace the master cylinder and the release cylinder. I had to take it back a couple times before because I had issues with the clutch pedal sticking to the floor. So they would bleed the lines out then it would do it again. So they replaced the master cylinder again, but still the issue kept coming back. They said they used a different bleeding method cause they didn't know about the "line booster" is what he called it. He didn't know the exact name. I'm guessing he meant the clutch damper by the way he explained the location of it.

Thats what I was think especially seeing how its been in for a clutch job but the guy was saying the smell was indication of a clogged or defective catalytic converter. Which I know will hurt the performance of a vehicle but not like this. I had no power to the wheels yet my RPMs would raise high and fast. My clutch disc was completely shoot when they pulled it out. The transmission worked fine before today. It went into gear and drove smoothly. It is a transmission shop so they are handling the repairs. They haven't recommended me to another shop yet.

I might add that the shop has been very patient with everything and hasn't charged me a dime for all the issues. Even when replacing the master cylinder for a second time they never charged me....

Oh I see, I still think that the clutch is slipping which is what your smelling. I would recommend the use of oem master cylinders and that they are bled correctly other wise they will leak internally and the pedal will randomly drop to the floor again. Make sure they are resurfacing the flywheel correctly as our flywheels have a step which also needs to be a counted for. There are several detailed post on this so that you understand this issue. That's cool that the shop is being understanding too.

if they took too much material off of the flywheel then the pressure plate wont be able to apply enough pressure....

Honestly it really sounds like your mechanic doesn't know what he's doing when it comes to a DSM. Three times back for a clutch/flywheel job is unacceptable. It's not a difficult job, but there are small DSM specific details, some of which have already been mentioned, that someone inexperienced with these cars aren't gonna know about.

I'll be sure to mention to them that the parts have to be OEM parts. Research I've done leads me to believe the same cause if it was a catalytic converter the engine would not have an increase in speed.

I don't think thats the issue cause they resurfaced it awhile ago.....

I 100% agree!!! Its getting old real quick!!

Take it somewhere else.

Also, measure the step height of the flywheel, especially since they resurfaced it. It could easily be out of spec of 0.608"-0.612" step (measured from top of legs to friction surface across the entire friction plane).

As well, confirm the clutch master cylinder / pedal assembly adjustment. It could be over-disengageing with pedal down and putting pressure on the clutch at pedal up causing partial disengagement / clutch slipping.

Either way, something is out of adjustment, or over machined, or they were really dumb and put the clutch disk in backwards, or you have a severely worn part, or they are missing the starter plate or the bellhousing bolts are not all in or loose along with the bellhousing dowels.

A proper professional or experienced DSM/Evo mechanic should be working on this. Not some random transmission shop.

So an update, the shop called and said the car has been working fine for them. It's not showing to have an issues. They've taken it on several drives and let it sit, then drive again and still no issues seems to come up.....wtf is going on here. How could it be doing it one day then perfectly fine the next? Any ideas?

What's the name of the shop? I had transmission work done near San Marcos.

 

[VolcomDSM]

I actually took it to a shop in Austin cause I work in Austin, all though I live in San Marcos. The name of the shop is Eagle Transmission.

What kind of car is this? non turbo? turbo with an aftermarket turbo? awd? fwd? if its awd the center diff could even be slipping.

It's a 97 GS-T Spyder. Has turbo and the car is completely stock.

And your sure that your not just spinning the tires right?

Haha I'm positive! I know what spinning the tires feels like

This all still sounds off to me, I hope they are using quality parts. I learned my lesson on that the hard way, if you know how to take off the transmission on your car i would suggest doing that send to TMZ or any reputable transmission place that knows these transmissions inside and out, and you can know for sure it was done right with proper specs. Also when installing a new clutch master cylinder don't forget to adjust it to have the most throw when pressing on the clutch. The shop sounds nice for them not to charge you more (as they really shouldn't anyway) but you've got to know when to call it quits with them. Who knows they might just be learning as they go.

 

[Vegas Smith]

I know a guy with a small DSM shop in Kyle. Hit me up if you want his contact info.

 

[boostdawd]

Do u know what brand clutch was used? 3x is a little excessive.

I wish I could remember what parts they said they used....I'll have to find that out again and let ya'll know. Yeah they are really nice but youre right and I'm at the point to call it quits but I payed a lot of money and shouldn't have to pay again.

Not off the top of my head but I can find out, and it has been 4x now
