On top of that, AGA was very cool about it and replaced both rods free of charge.
Replace transmission mount, surprisingly it was not

A few months after while replacing the clutch, I also replaced the transmission mount, surprisingly it was not to bad, I also inserted Function First, yellow inserts and are very happy with the results.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I�ve put nearly 12k miles on my 03 c4s since buying it last March. Several RL members have commented about sagging tailpipes upon seeing photos I�ve posted, and I occasionally experienced shifting issues, usually going from 2nd to 3rd. Shifting in general hasn�t been crisp, but having not driven any other manual Porsches i had no frame of reference for what shifting should feel like, until now.
Just picked up my car following installation of OEM motor mounts. Even though i only drove for 20 minutes in constant rain, shifting was incredibly smooth, crisp, and effortless. Kicking myself for waiting so long. Worth every penny!!
I have an 03 c4s and am wondering if my motor mounts might be sagging. I didn’t think they were that low, but certainly could be. Did you take before and after photos?
Now you need to finish the job. The tips have adjustment to fine tune your aliignment, and tuck them in closer. If you drive in winter conditions you may just want to leave it.....
I had the same response when I changed mine...even started shifting better.
However
, I would urge you to adjust the shifter as well. It's pretty easy and you might be surprised just how much better it shifts. Even though mine didn't have too many problems shifting, I could still tell something wasn't quite right. Bought that $10 shift lock tool (don't remember where), pulled off the center console, and did the adjustment. On the next drive the car shifted like a new car.
what would be the telltale signs of transmission mounts being shot now that motor mounts are new? appreciate your input. car only has 33k on it now. biggest issue i had pre new mounts was a failure to engage 3rd from 2nd on rare occasion, felt like it wouldn't let me in, and going from 3rd straight down to 4th it felt as if i was moving along the right edge rather than down the middle, if that description makes any sense.
thanks again.
I believe a special tool is required to do this but I could be wrong.
I've got a brand new set of engine mounts sitting on my desk awaiting installation. Wonder if it will help my shifting as well, although I think I need cables regardless.
When installing motor mounts, if the engine is sagging because of the old mounts; how do you know how high to jack up motor when installing new motor mounts?
i believe another symptom could be unusual vibrations while idling. I didn�t have that issue but shifting issue was very noticeable. I don�t see any sag in your photo.
I like the method you used to measure this from underneath. Mines a daily driver so I�ll wait until the snow and ice melt before I get under the car and try this. Thanks for the pictures.
There are a couple of guys on this forum who can rent you the tool to remove your tranny mount with the transmission still in the car for not much money. They are pretty much all shot on these cars if they haven’t been replaced. If your motor mounts are shot your tranny mount is probably shot too from the movement allowed. You can have issues shifting too if it’s totally out. My car drove fine but all my mounts were destroyed. The tranny mount was literally ripped in half. I replaced it with an Oem one and a function first insert and did the WEVO engine mounts and have been very happy with it. Most 996’s are just getting oil changes at this point for maintenance and all of the rubber parts and long term stuff are about 20 years old now. So pretty much everything is due. Having a bad tranny mount can wear your engine mounts faster too and vice versa.
I also replace my motor mounts for great results. But I went a step further and filled in the new motor mounts with 3M Glass Urethane Windshield Adhesive and really like the results. More precise feel over all.
A few months after while replacing the clutch, I also replaced the transmission mount, surprisingly it was not to bad, I also inserted Function First, yellow inserts and are very happy with the results. If you never track the car, this may be an overkill, they also have other softer inserts that you can try if you want.
I rented the tool from member "dkraige" a couple of years ago but I'm not sure if he's still renting. My old mount at 20 years old and 39k miles was intact but really hard and brittle. Swapping the mount was pretty straightforward IIRC (i think i watched a YouTube video too).
It was more like DK RAGE after i sent him back the tool with a bent rod. They are mostly in bad shape two motor mounts out back and the tranny in front it really gets abused. Preventive maintenance is always good on our cars!
^^^ That's too funny! ^^^ Not quite sure how you'd bend one of the rods, (probably over tightened one without tightening the other) but whatever... In Dkraige's defense, the bolt's/rods are super expensive to replace (AGA wants over $200 for a set
) as they make them out of special acme threaded rod. They actually sent me a replacement set when one of my renters stripped one out... That's what the deposit is for...
You don't "jack up the motor" per se'... You're just supporting it so it's not hanging on the mounts (just to get the weight off the mounts so you can unscrew them and so the motor doesn't fall on the ground when you do). So to answer your initial question, 1/8" - 1/4" should do it. You don't want to be "lifting" the whole back of the car via the engine. As soon as you see the rear of the car start to lift up, stop. Now you'll be able to remove the two large (18mm?) bottom nuts that carry the weight of the engine without the engine dropping. ** you'll probably need to spay them with some PB Blaster or similar (liquid wrench, WD-40, Kroil etc.) a day or so before you're ready to change them out. Have a large 1/2' ratchet with breaker bar or impact gun handy too they can be tough to remove. You'll want to remove one mount and replace it with the new one before moving to the other (so the engine isn't floating freely on the jack). Good luck
I don�t know Deezy�s story on what happened so I can�t say if what happened was his fault. He can go into more details if he cares to do so.
But, what happened to the tool is why I only lend tools to a few people in my circle... my sons and a couple friends who are very adept mechanically and can/will replace the tool if damaged or lost. Most men today can�t even use basic hand tools. I see it ALL the time. They have never built or made anything in their life and can�t even identify basic tools. They don�t have a �feel� for how the tool is working and don�t even understand what they are doing or why. They go through what I call �monkey motions�....basically, imitating what they see or read on the internet without truly comprehending the why. Want to see something hilarious and terrifying at the same time? Watch one of these guys working on basic electrical issues.
The internet is a great source of knowledge. However, having the knowledge and applying it correctly are two different things
There's fault, and then there's fault... When I rent my tool out the renter pays a deposit to cover the entire cost of the tool. This insures that they don't abuse it (or they wind up buying an abused/damaged tool). In my case, I've never had to charge anyone any amount against their deposit. Even in the case where the guy stripped one of the rods, I felt as though it wasn't his fault - he wasn't abusing the tool. On top of that, AGA was very cool about it and replaced both rods free of charge.
Couldn't have said it any better. You either got it or you don't
Not to derail this thread but I worked at an auto part store when I was younger and a customer came up to me and ask for starter fluid, so I grabbed him a can and he proceeded to ask "so I just spray this on the starter?"
I actually stood there for a second and thought "you've gotta be f***ing kidding me" then I remembered my professionalism and just went to his car and showed him how to use it instead.
I replaced both engine mounts and transmission mounts at the same time last summer. 17 years and 63k miles on them.
Biggest improvement was the transmission mount. My car is a Tiptronic so the mount is easier to change. One tell tale sign of the mount shot is a loud "THUMP" from underneath the car at WOT when the transmission shifts. Mine was pretty much gone and the new one was night and day.
