Does anyone know a link to a description of the process to remove the gearbox? I have synchro and pinion bearing issues so I figure gearbox overhaul time. First removal, then I need to find a good shop for the overhaul.

I know you can find it under 944 clutch replacement as the box has to be removed on the 944. I know the 944 has a 5 speed, but it should be about the same. I have done it on my 944, but have not on the 68.

Clarks garage has the instruction on removing the transaxle to do a 944 clutch, that should get you most of the way there.

I had a shop remove mine from the track car & send it to the RS Barn. Pete & Max did a great job. I have found a 968 specialist in the Tampa area, German Specialties, here on the forum. Leo said he love to work on these transmissions. I suggest using someone familier with this 6 speed.

Removing the transaxle from these cars is doable for the DIY'er, but definitely not a fun job. Just removing those wretched 12-point "cheese head" bolts that hold the axle shafts to the transaxle is enough to drive a sober person to the nearest liquor cabinet. The rubber CV boots sit very close to the bolt heads, making it difficult to get the wrench on the bolt heads in a perpendicular fashion. I can't remember the last time I stripped a bolt in my long lifetime of working on cars, but I ended up stripping three of these beauties. And that's just the beginning of the fun. A local shop erroneously told me I had an input shaft seal leak, so I was planning to remove my transaxle to replace it, but upon closer inspection, I found that the leak was actujally coming from the seals behind the half shafts, so I ended up leaving the transaxle in the car, I know Kwikt (sp?) has done this job. It just really requires a lot of patience. Good luck.

I just took mine out last weekend, the instructions in the 968 workshop manual is pretty good:

• Disconnect the back up sensor
  
  
• Disconnect the shift linkage and slide the linkage bar forward
  
  
• Disconnect both axles shafts
  
  
• Slide the driveshaft connector to into the trans bell housing (note take the bolts all the way out, there are keyed in)
  
  
• Support the trans with a jack or trans jack
  
  
• Support or block or support the torque tube
  
  
• Remove the 4 bolts between trans and torque tube
  
  
• Now the trans should only be hanging by the two trans mount bolts
  
  
• Finally remove the two trans bolts
  
  
• Slowly let it down and pulling back making sure to clear the shift linkage.

Question, can just the transmission rear sections be removed,( the rearward iron and aluminum cases) not the whole trans-axle? A track day missed shift as resulted in a second gear problem, extremely hard to get into second and almost impossible to get back out.



No metal in the drained oil, I'm thinking either bent linkage or a damaged/bent shifting fork!



Thoughts?

Doing a site search and reading about some of the transmission second gear problems, I'm thinking more serious issues than just a bent linkage or fork. Looks like I'll be dropping the whole trans axle.



Any thought on a rebuild shop or possible purchasing a used unit?

Best dismantler.

Just responding to the question of dismantler. Someone posted this site on another thread, interesting web site: http://dcauto.com. They have a trans in stock, "Number 01E300042J $2,500.00 G44.00 Replacement transmission complete"



http://dcauto.gotdns...7988#01E300042J



Also, here is my ongoing list of dismantlers to search around, haven't communicated with them in a few years though. Can't say which are best or worst.

I had the same problem at VIR - lost second gear synchro. Getting into second gear became impossible, and first gear was really sticky. First became looser after the box cooled off, so I was able to limp home shifting from first to third.



Rebuilt by Precision Motorsports Racing in Califon NJ. They are a top-notch shop and do a lot of 944/968s.



Good luck getting parts - new OEM transmission parts are nearly unobtainium. <img src="/forum/images/smilies/968/sad.png" class="smilie" alt="" />

I've got a used box coming, no <acronym title='Limited Slip Differential'>LSD</acronym>, hopefully this will allow me some time to how/what/where to fix the old one. What type of <acronym title='Limited Slip Differential'>LSD</acronym> are you running, I'm thinking I will add one to this box before installing it.
