I'm getting some sort of weird transmission noise when I'm in gear. It's a high pitch squealing sound not unlike a cricket. It's only when the car is in gear, throwing it into N or P makes it go away. I've had a look under the car and all I can tell is that it's coming from the trans.
Anyone have any idea or similar experiences?
Trans mount has been replaced 6 months ago. |

Are you sure this car hasn't had a thrashing? |

Yeah, fairly sure, and I've haven't given it that much. The noise kind of sounds like something rubbing against rubber, maybe something to do with the trans mount again?
Why, what are you thinking?
I suppose the worst case scenario is that I'll need a new transmission. Even if the car has been thrashed, which I wouldn't think so, I've spent too much on it so far to worry about getting rid of it. I'll just have to get it fixed. |

The mount just holds the box, so would not be squealing.
And yeah, I would do the same  |

Hmmm,
Well I've now got it booked into MV Auto's to check it out, but they can't fit me in until the 12th as they are closed down next week. Hopefully it just needs a service or is something minor fixed. It is possible it's the bearing in the drive train?
I've never been really happy with the trans, I've always thought that something would need to be done with it. So I guess if it's dying I'll get a second hand one and shift kit with a tranny cooler. Really the only thing I can do. Hooray another 1k+ I'll be spending on it if I do need a new trans.  Fingers crossed I don't.
I guess that's what we get for owning Soarer's Peter. I might swing by the shop for a visit on the way back from MV's if that's OK. Figure you need to see the car now. It's so much better than when we had the meet. 
IF you could run me through putting the braided brake cables on I'd appreciate it. |

No problem! Always happy to have Soarers visit and the brake lines are easy. |

Sweet, I'll email you so you can be ready to be impressed! Mwhahahaha!
I did actually find a picture of the drive train assemble all sectioned up with part numbers and the like. It showed a bearing in the center and I remember someone writing that if your trans mount goes it could be putting extra load on the center bearing and that can go.
HAHA, found it!

So how much would I be up if I have to replace the trans? I'd be looking at an Auto, don't really want to manualise it. |

2k drive in drive out to do a full rebuild, including valve body mod and torque converter overhaul. Most places don't charge to lift the stall speed because they have to split the converter to inspect and make any repairs regardless. |

I'd probably prefer to drop a second hand box in... how much does one of them go for.
You can get all the part numbers from the soarer part numbers CD... if mine ever comes that is... |

It's part of the drive train assembly and contains the bearing I'm referring too that could be worn. |

I made the assumption from your first post, when you said it makes a noise in D but not when you put it in P or N, that you were stationary.
The centre bearing in the tailshaft will not be rotating when you are stationary (with the exception of a burnout) and as such is unlikely to be making said noise.
I'd be more likely looking at the first gear clutch bands in the trans or possibly the torque converter.
Does it make the same noise when you are driving?? |

Shift kits can add a little whiney noise to a good tranny but not much.
I'd go the 2nd hand 'box but reco'd aren't too bad in price for that extra confidence in it.
Shift kit and cooler are a must as I'm sure Mike will let you know. |

Dan, yes same noise when I am moving. Really seems to be only after the car warms up.
I'm hoping it's something easy (and cheap) to fix.
I'll defiantly be going the second hand box with a Stage 1 shift kit and cooler. If that dies, which is shouldn't) I'll look at getting a recond box.
Checked trans fluid last night and it's not too far off needing a change. |

I've never heard of it with a Soarer but some cars can be prone to cracking or breaking the flex plate that holds the Torque converter to the crank (all drive goes through it, sometimes called a Drive plate).
This can sound something like the end of the World when the crack gets big but is basically easily fixed, just have to pull the 'box out and change the plate.
Definitely something to check while the 'box is out. Merc's tend to crack around the mounting bolts for both the converter and the crank. |

I guess I'll find out on the 12th. I'll inquire about the shift kit and cooler at the same time I'm there. I'm very interested in one, especially if I can drive it normally as well as have that extra kick when I need it. Stage one it is.
Do shift kits cause any extra load on the diff or any other parts? |

Up to a point, yes...and no.
If driven hard then, yes the tailshaft, diff and drive shafts will tend to cop a pounding but that shouldn't be all the time and with the newer modified stage 1 kit the changes can still be very smooth if driven that way (this is why I wouldn't buy a 2nd hand shift kit unless I knew it was the later version. The early stage one is harsh ALL the time).
For any gain there has to be a cost and at least diffs are easier to change than gearboxes! It seems to be them and not anything else that gives way when pushed. A rebuilt Torsen or similar shouldn't mind too much though. Even a good standard diff will be OK unless you deliberately give it a hard time.
Bear in mind that a good standard diff is 15 years or so old now and general wear and tear is going to kill it soon enough unless it gets regular oil and maybe some new bearings and stuff. |

I'll only really only be using it to kick people's ass off at the traffic lights and, when I get some rear end noises sorted, maybe a track day or two.
I'm sure I'll need to be replacing my diff eventually. I'm just waiting until it dies to get a T2 or something similar. Hoping my transmission isn't dead though, then I'll just get the shift kit and cooler installed.
I'd expect some kind of wear though, I mean your changing something to do what it's not designed for.
I'll see how I go, with a little luck I could be shift kitted up before Xmas... |

Well Mark has been a HUGE help to me the past week. Thanks so much, good to have someone that has such a great knowledge base to draw from. Sometimes I think I don't contribute enough to the forums and I ask too many questions.
I have been toying with the idea if a shift kit for almost 9 months now. I look forward to see what it's like when it's on. Just getting a bit ancy about having to wait until the 12th to get that noise looked at. It had to pick the week that MV's are having off... so typical of my Soarer. Just know the right time to start with issues. Like my serpentine belt, thank the lord for belt lube! |

As far as I can tell the shift kit actually reduces gearbox clutch wear by shifting faster. Any increased wear on the drivetrain after the 'box is mostly down to driving style. A standard 'box can destroy a standard diff easily enough as quite a few have proven. The Torsen should be a bit tougher to break just because you gotta spin both wheels and that takes a heap more power but it still does have the same crownwheel and pinion gears to transmit that power. |

I Type 2 Torsen center is what I would look at getting. Not that I'll destroy the open spinner any time soon, it will probably die within the year though.
Well I'm convinced that a shift kit is what I need! |

Ashley;
head up the MV Automatics at blackwood
Mike is over seas until 7th december but when he gets back he can sort it out for you.
Some times the planetary gears in the box will make a winy noise.
a squeely noise can come from the oil pump . |

Yeah, I'm booked in to get sorted on the 12th. I'll have to get them to do a trans service soon as well, don't know when it was done last. |
