Where can I get a 951 Gearbox?

[PorscheG96]

I've been checking Rennlist for a while and I'll be checking with Kevin's buddy hopefully, but does anyone here have leads or other ideas where I can get a 951 gearbox cheap? I've seen some crazy instances where someone bought a gearbox from a wrecked car for $200! I wish I could be so lucky. I can't afford to have my 6 speed Getrag rebuilt for a while [pinion bearing], so a 951 5 speed is my best bet for now. Thanks guys! -Trevor

Sold a 951 Tranny on Ebay for $500 or so + shipping. Before We put it on people were offering 325 -200 I Laughed and said I'd put it on ebay.. a pretty good judge of what the maket will bear

You sold a good 951 transaxle for $500?

Did it have LSD? If it did you could have gotten $1500.

what abou the 5-spd from a s2 or an 944s, or even an n/a? lot's more of them around.

Ok, I feel another question coming on! I was under the assumption that the weak-point in the NA trannies was more-so the clutch's low torque tolerance than the gearbox, but I've seen how many problems Ahmet had with his NA gearboxes [3 of them] with basic mods like cams, ignition, and exhaust. That's why I doubt that the NA gearbox will have a chance holding up to the 968's torque. I know little about the S and S2 units...except that they have a slightly higher final drive than the NA, but with the actual 951 gearing...just a different pinion to make it shorter or something along those lines. Will any of these hold up to the torque, or am I correct in thinking I need a gearbox from a turbo for reliability reasons? -Trevor

for what it's worth, renegade hybrids (v8 conversions) claims the stock n/a trannies are acceptable for v8 conversion. i have heard of some problems with stock trannies handling that much tq, but the 968 is nowhere in the same tq league as a v8. an easily obtainable (and cheap) n/a tranny may be worth a shot.

Have you talked to any of the people from 968.net? I heard that if you ***** enough, you can get the pinion bearing problem fixed at a dealer under warranty, even if your warranty is expired. Something about the fact that it's a known manufacturing defect.
I'd check 968.net to see how to go about getting Porsche to fix it for free.

I cannot say for sure my problem was more power. That thing never made anything significantly higher than stock. I don't ever speedshift, I do abuse the diff, but I've had stuff like exploding 3rd gears, or broken diff bolts in the transaxle, I don't know how that's possible to do. In defense of the Porsche 944 NA trannies though, besides one rebuilt transaxle (many used parts I'm sure) all of them were used, which means possibly abused. Anyway, I wouldn't put a 944 NA transaxle in that thing personally.

Why don't you, go have that thing rebuilt? Must places that work on BMW, or VWs should be able to rebuild the thing, it's REALLY not that hard, could cost you, but no more than $1k, if that (don't know how prices are around there though).

However, if you do decide to get another transmission, I'd be an interested buyer in that 6speeder you have. Does it have LSD?

I was quoted over $3k for a rebuild. My whole intention here is to keep the 6 speed, and I simply can't afford to have it rebuilt right now, that's why I'm looking for an alternative cheaper gearbox to use so I can drive the car until I can get the 6 speed repaired. ****, If I could get the damn thing rebuilt for a thousand bucks, I wouldn't hesitate for a second! The place I'm going through must be ripping me off pretty badly, but I'd always heard that gearbox rebuilds are this expensive. The box does not have LSD, and that's another reason I planned to wait. I was gonna buy a used Torsen LSD and have that installed during the rebuild. So it looks like either a turbo tranny, a cheap rebuild, or let the car sit for a LONG time... -Trevor

Todd, I forgot to address what you said. I've been following 968.net for over a year, and I was well aware of the whole pinion bearing issue LONG before I bought the car back in february. Something that people fail to mention is that these gearboxes can't be fixed. I purchased my car with a mileage above the 'normal' breaking range of the Getrag units, but it started the characteristic whining 15k miles into ownership. Little to my surprise did I learn that this is the SECOND time the box is experiencing the bearing problem, but luckily it has never failed. So it looks like I'm gonna be having to rebuild this box over and over again until I get sick of it or the damn thing fails...rebuild w/ new bearing is just a temporary fix.

I just found this...Don't know if it is still available...

I got my 952 tranny last year from Autometrics for $1100. It has the LSD and oil cooler. I'm not sure how much power the N/A clutch can take, but I have a Centerforce DF for the N/A that can handle the 310+ hp that I force thru it.

[Britwrench]

Your trans failed the second time because it wasn't repaired properly. These trans are a real pain to rebuild and take a lot longer than the book time = shortcuts. The pinion bearing set up takes forever and probably wasn't done, just new bearing installed.
Go back to the repairer and complain.

BTW No-one is prepared to rebuild this type of trans for $1000; with parts and labor it's not possible.

[adrial]

I'm gonna have to agree with Britwrench regarding the fact that the tranny was not repaired properly. The pre-load on the bearings has to be set properly (which was not done from the factory..I believe). If the pre-load is not set correctly and the bearings are just replaced...then the problem with return repeatedly.

As far as cost to do it..I think $3k is about average...but thats coming from memory so dont take it as fact...

Check the rennlist classifieds...there's a guy selling a 951S tranny for $500...its got 300k miles on it, but should be fine for now at least..The title of the ad is "Turbo S disperate" or something

Good luck,
Adrial

[PorscheG96]

Yeah, I contacted the guy about the Turbo S gearbox...he told me that the synchros were in poor shape, so there was obvious grinding when changing gears. I was fully prepared to consider this unit but he sold it just as I was asking him questions about it. Oh well...I'll continue looking. -Trevor
