I wouldn't have thought that the band would need adjusting after only 30k, but it has to be done. Harvey.

Re: symptom help request
My transmission failed somewhere around 30-40k miles. Not completely sure, the prev owner said it was replaced somewhere around 70K. I got it with 101k and adjusted the brake band after a couple weeks and it wasn't enough to save it. I know he wasn't bsing me either as I had everything apart awhile back when I thought the motor knock was possibly a cracked flexplate and it was obvious enough to tell things had been taken apart before.

Re: symptom help request
the apply pressure and high clutch pack in a stock spec transmission is borederline at best. Any rebuild that doesn't address all the seals (there are a couple special order ones not included in an overhaul set) is a candidate to start right off on the wrong side of that border and keep heading south as the high clutch wears.
There are two sides to that timing between the band releasing and the high clutch grabbing. If the high clutch is slipping it will take longer to lock up. Part of what makes my transmissions shift so fast is that the stronger clutch packs catch faster. Probably the biggest hint to telling if it is only the brake band or if it involves the high clutch too is your performance in 3rd and 4th. Just because the car keeps moving doesn't mean it isn't slipping; how good is acceleration in 3rd and 4th? how quick is the 2 to 3 shift? What rpm are you at at what speed in 3rd? Asking and answering those questions acurately can help you figure out what's going on. Access to a healthy SVX can help with the acuracy of those assesments. |

If the high clutch was to slip in 4th, the box would go back to 2nd, and if it slipped in 3rd it would go back to 1st. Now I am not saying that your high clutch was OK, just that the symptoms that you describe, are not for a failed high clutch. Harvey.

The new posts on this thread have me feeling a bit better. The other thread with the posts making it sound like adjusting the brake band was only going to delay the inevitable failure were not good for my nerves...sounds like the issue i'm having is totally different. So if the brake band is adjusted my transmission should be ok (for as long as these things last)? Last edited by oregondave; 03-23-2009 at 10:16 PM. |

Re: symptom help request
It's possible but not likely. The friction material on a brake band isn't all that thick to begin with and the brake band servo has something like half an inch of travel. Generally, if they are worn enough to cause impropper operation they are pretty much shot. Also, the brake band should be releasing quickly to begin with and it's reasonable to assume the high clutch is getting slower to catch.
As things slip they wear rapidly. If you are hoping to not have to change transmissions you need to adjust your tps and brake band yesterday. |

Re: symptom help request
okay so I had the brake band adjusted and the tech said it was 3/4 of a turn out of adjustment (loose). He checked the TPS and said he got a reading of .53 which was within specs (I see that many here like .48-.50).
The car shifted good before but seems noticeably better now. The shifts are firmer and smoother. I guess we'll see if it flares again... |

Re: symptom help request
Thanks! so at this point would it be safe to install your tcu or the quick change mod? would it put more pressure on the brake band or would it help preserve things?

Re: symptom help request
My tcu is just to make the car drive better and improve fuel economy it doesn't do much to make it last longer. Having me rework a valve body for you would greatly help your transmisison last longer and make it shift much faster.
