Coverage and how to read this overview

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.

POST 1 / ORIGINAL POSTEROriginal post

I recently had the IMS on my 2001 996 C4 upgraded at a local shop and I've driven the car about 500 trouble free miles since then. Literally overnight, the car started having difficulty shifting into all gears. I drove it very briefly yesterday (first sign of symptoms) and took it immediately back home. After inspection, the shift linkage and shifter seem fine. The resistance is coming from inside the trans. I have extreme difficulty going into all gears including reverse. There's no grinding or unusual noises, just an enormous amount of resistance. This happens regardless of whether the car is on or off. Once I've muscled it into a gear, it's relatively easy to go back into any gear that requires the same direction for the shift pattern. For example, if I go into 1st, then I can easily go into 3rd & 5th, but not 2nd, 4th or 6th because they require the opposite direction. The opposite is true if I select 2nd, 4th, or 6th. Hope this makes sense. While inspecting the linkage at the trans I spotted one of the primary trans bolts was completely unthreaded and dangling loose. It's a miracle it didn't fall off completely. See the picture below, the loose bolt is location G on the diagram. The question I have is this; could the missing bolt have caused an alignment issue with the trans and could it be the cause of my shifting problems? Anyone have suggestions as to how I should approach the shop with this issue? I believe they have responsibility in this because the work wasn't done properly. I've had the car for about 2k miles and never had a single shifting problem before this.

POST 2Original post

Check this clip and make sure its not broken if you havent already. I had the same problem after a clutch change and this caused it all. But if all other bolts were on tight and that one was just loose I don't think it would cause those symptoms. Check the mount bolts on the trans and motor just in case

POST 3Original post

Could be a failing clutch slave cylinder and coincidental. Or maybe they left the slave mounted and disconnected the hydraulic line and there is air in the line and it needs to be bled? I had issues with the bolt in the position you show. For some reason, that specific hole was full of crud and the bolt would not thread all the way in. I shot some Brakleen in the hole and swabbed it with Q-Tips but had to run a tap through it to clean it out.

POST 4Original post

Dealership had problems getting my transmission off after any Indy I brought my car to over torqued the bolts. I'd be weary of un reputable independent mechanics and 996s I've had issues. Alignment of the shifter is important pull out your console (max one hours work) and use the special tool to check the alignment a few threads out can make the difference.

POST 5 / ORIGINAL POSTEROriginal post

Thanks for the suggestions. I had the center console out yesterday and inspected the linkage at both ends and nothing appeared wrong. I'll look into alignment of the shifter next, however the resistance to shifting into gear appears to be from within the transmission when I was actuating the lever on the trans itself with my hand. I don't think the linkage or shifter are involved here but it can't hurt to align the shifter. The shop I used is considered one of the more reputable indy shops in the Chicago area. They have multiple locations and some of the highest ratings so I assumed it was in good hands.

POST 6Original post

Quotes source post: 13289247

When you discovered the missing bolt you should have had the car back to the shop that did the work and have it look into the shifting issue. You could keep that you found a missing bolt to yourself to see if the shop would own up to this. While I don't think the missing bolt is the cause of the shifting problems it tells you something about the shop if it owns up to something it found wrong with its work. The fact the shifting problem is asymeterical suggests to me it is an alignment problem of the shifter. The shop failed to properly (re)align the shifter hardware or did but something has moved out of position. That a bolt fell out does suggest the tech was not thorough in his properly tightening down the hardware.

POST 7Original post

The shift cables have a habit of coming out of their mounts on the transmission. Its quite common to use zip ties to hold them in place. Check out the pictures in this thread and you can see the zip ties that have been put in place. Maybe your cables have come loose at the transmission. If so, its a very easy fix.

POST 8 / ORIGINAL POSTEROriginal post

I know this thread is long since dead, but I want to update everyone on the solution to my shifting issue. Long story short, the shop owned up to the missing bolt and fixed it along with several other items. Upon further inspection, the shift linkage was worn and needed replacement. Additionally, the linkage mounts were not holding the end of the linkage in place properly, and lastly, the car had an aftermarket short shifter installed that needed to go. It shifted like crap and had a lot of play. I replaced it with a 997 shifter that I upgraded with GT3 style aluminum bushings (love the feel of this shifter!). The items above made a substantial improvement, however there was still some resistance getting into gear on occasion. I discovered my motor mounts were worn, and one side of the engine was hanging lower than the other. After replacing the mounts the car drives and shifts like new. I'm now 1 year into 996 ownership and the car has gone 6k trouble free miles and it's 100% up to date on maintenance. I couldn't be happier.

POST 10Original post

Irontonic, Thanks for the update details. So often people do not bother. Listing the multiple issues helps others who try one solution -like the zip ties and then say "it did not work" !. Actually ,it did but there were 3 more unaddressed problems. If any one is trying the zip tie fix- and that is the only problem, it is o.k. to use low quality zip ties to test. If it works , consider using better quality ones. And if like Mr.Irontonic ,you have a bad shifter and a limited budget search about Ben006 on the 986 Forum. He has an alternative that seems popular. http://986forum.com/forums/diy-proje...t-shifter.html for the benefit of others with this 'pop-off' problem. There is one big precaution to take - use zip ties that are really high quality. The cheap ones go brittle quickly and snap. http://www.cabletiesandmore.com/extr...ature-ties.php http://www.nelcoproducts.com/cable-t...-12-cable-ties http://www.nelcoproducts.com/cable-t...es-18-lb-50-lb http://www.nelcoproducts.com/cable-t...mer-cable-ties
