GS transmission mount after 10k km ... is it normal ?

I just left my Viggen in the shop for repair warranty claim. The reverse does not engage, its almost like I was pushing it against the lock, just the other way around. Only moving the car backwards and using force helped to shift. The reverse was rebuild 4 months and 10.000 km ago after a clutch failure and was hard to engage since then. The mechanic says it was because of the GS mounts that were installed at that time too.

One week before when I was changing oil, I saw that the tranny mount looks strange. What do you think ?




I should hear from them next week after they remove the tranny and send it to their external tranny mechanic. I made myself clear that I don't expect to pay anything for any reason, they were quite defensive. Those 4 months ago I let them put there GS mounts, full powerflex, koni sports kit, quaife lsd, GS steering rack clamp ... and told them replace anything thats suspicious ... I didn't expect it to end like this and so soon
Since they were using the GS mounts as excuse for the shifting un-easiness (the GS stuff is not used around here, so blame the unknown...) I'm somehow expecting them to blame it again, the more when they see how it looks...

I am starting to feel like I have bad mounts and I have GS mounts.

Woah thats really odd. Have you called Nick at the shop yet? If not I would give him a call and talk to him about that mount. I'm sure he will see this post though.

Ouch, that is definately not normal. I would think these GS mounts should have a longer service life than stock mounts. It looks like that cut through itself no?

I've had mine on for 12k mi now, and it looks just like it did the day I installed it.

Maybe a little dirtier, but otherwise it's holding up well.

How are the other mounts? Most specifically the lower transmission mount?

If any one of the other 2 mounts were/are shot then you're going to wear out the remaining mounts very quickly.

NahumCC: I wont probably call Nick, the charges from Europe are quite high (and I dont trust my English so much ). I'll write him an email soon, I started here because the more people see it the higher probability someone has already experienced something like it.
I dont want to bash GS or my mechanic, I'm just trying to find out WTH is happening. Something has pushed the mount and maybe it had no chance to withstand it.

JK9000s : I bought both GS mounts and had the third one - the bigger round hydraulic one in the back replaced as well. It was not completely bad, but because of the reason you already mentioned a new one was put there.

A tranny mount should not wear out with only 6000 miles, 10 k on it. I'd have to say you had a bad mount to start, especially if your others were replaced at the same time.

Many other SAABers, some that I know and have seen personally, have equal or more mileage on their GS trans mount with no issues at all.


Good luck, sounds like a FUN VIGGEN!

Have you thought about having the car done up like Philip's car?

Heuschmid? Its in Germany, but I don't know how far of a ride that is for you, or shipping costs of the gearbox to them.
http://www.heuschmid.de/

They seem to have good experience with these matters. I would not expect the mounts to be suspect, has any horsepower mods been added to the car, something to justify the lsd?

I just finished writing a mail to GS and found out that I missed some information here.

It is a MY00 3dr Viggen currently with 140k km, I bought it with about 80k km 2 years ago. According to the papers it should have Hirsch Stage 1 upgrade (since about 40k km, I need to look in the papers). Official numbers should be 181kW instead of 169kW and 380Nm instead of 250Nm of torque. What is more important the curve should be more flat ... and even I haven't dyno-ed it, this is clearly visible.

The LSD ... it was an impulsive buy after I found out the sale price at that time. And as you can see from the mods, I'm trying to go for more control not really for brutal power - its a daily driver (check the mileage/year ... kilometrage sounds odd )

Ah I didn't notice your location. That would be one expensive phone call. Something else had to have been done to the mount by accident to damage it.

Papluh, if you want to verbally communicate with Nick T., I believe he has Skype, which is free software. http://www.skype.com Perhaps you could set up an appointment with him where you called him via Skype. Good luck with your transmission problems. I can tell you I have personally spoke with him on the telephone, and he's a very friendly / helpful guy.

Kevin can sort this out tomorrow.. I can tell you this is a very odd failure.. I just had the trans mount out of Eds car.. It looks perfect.. and it is making 566nm at the wheels. (665 crank!) Long story but it involves all the teeth off of 5th gear gone on holiday.. Used 9000 gears.. Improper preload on reinstall.. Long story.. We are still here at the workshop with a completely rebuilt gearbox 14hours later.. and I closed on a house in that time too. Even got some other upgrades too. Leaving for soc in a few hours.

Mine is broke too, except I think I broke the engine mount side, passenger side and I have the upper 9k mount too! My engine rotated so far that the lower ac pulley and belt ground into the lower radiator hose

I did hit 33psi on a cold morning though, about a minute later I was smelling coolant and pulled over to find my engine had moved so much, the serp belt and pulley had contacted my lower rad hose.

I can now feel some slop in one of the two gs mounts, I am just not absolutely sure which one it is. I will investigate both this weekend.

I just got the word from my mechanic. the reverse synchromesh somehow got out of its place and was damaged.
They said 3 possible reasons
1. the GS mount was faulty, it has about 3cm / 1in of play in left-right axis. That could cause damage to transmission. They incline to this reason.
2. The damaged part was faulty. Thay had no problems with OEM parts like this.
3. I was supposedly doing some 'mean' stuff with the car like 180' turns under power and such or I cannot shift...

Workmanship faults were not even mentioned, but anyway under warranty rights and laws they can get only with nr 1 without being paid from their pocket (2. part was supplied by them and 3. they cannot prove and is absurd) ... so just guess which way it will go ?

But still being correct they told me to bring the original mount to see how it behaves with them. As they are still in pretty good shape (not changed at least for 55k km) the reason of fault was not there before. So lets hope we find something that has caused this issue.
If not I'll probably have to shed not so few Euro for tranny repair

Its sad but after another 2 weeks without viggen (about 8w together this year) I'm begining to ask myself if its worth it. Two C900s, one stock daily NA and one turbo for playing, will probably give me more driving time...

hey there paplah I do see that the mount did break
I have a set on my car which makes pretty good power 400WHP & has made more.... Ive never had a problem & it is my opinion that the issue with your mount would not have damaged your reverse synchro
I dont know what did but I seriously doubt it was the mount.....
IM sorry you are having so much trouble though it can be frustrating sometimes but hang in there it will get better
take care

The aftermath:

GS mount: Removed. I don't have a clue what happend, hopefully somebody will. We put it back together and remounted, engine side first as it should be done. After few km it has again started to push out the poly part. See yourself.



Transmission: The reverse synchro got out of the sleeve or something like that. No visible damage on it except few scratches. The transmission guy could not think of any reason why (or wont say any if it was his fault), therefore they cannot blame me or parts delivered by me ... it was for free this time

Anyway the reverse still does not go in smoothly about once in five or six tries. I have to wiggle with the stick to get it in or go through 1st. Also sometimes the lock does not pops out when in reverse and turned off, have to wiggle the stick again to release the key. I think I'll let somebody else look on it...
