Ok here it goes. I got my car back together a week ago, play with it in the shop after work and just generally check it over, everything seems to be normal. Trans has not been apart. Fri. nite I take it to a local track for some test and tune. My friends with me said that when i put the car in low gear they could hear a squealing sound similar to a belt. Sometimes they could hear it for a few feet after I took off. After repeated attempts to hear it I finally did. Once in the car with a helmet on you can't hear it. It also seems to me that once in gear it pulls the engine down more than it should ( I have not driven this car since last oct. ) So I may have CRS. So after a couple of passes ( car ran fine and e.t. was where it should be, I loaded up and went home. Sat. morning I pulled the trans and inspected every piece and found no damage and no wear. It looks like it did when I built it 2006. It had no metal or any other debris. I use the tractor fluid and run an ATI converter. Could something be going on with my converter? The car weighs 3,300 lbs and runs 6.0s. Oh yeah I also run a BTE 1.80 straight cut planetary. Converter and planetary are 3 years old. Sorry for the long post, I sometimes have a hard time with words.
Greg

I had a glide make some noise a few years back, everything looked great when it was taking apart so called around some said 1.80's are a bit noisey. I upgraded the pump in it and the noise went away. All though it looked good, ran good and repeated.

Is it a high pitched noise ?

David, I would say it is. But what is odd I have ran them all this time and never really heard anything. Why now?

Did you inspect the stator support to see if it is spinning? If it is definately not the trans then doesn't it just leave the converter?? You would think that if you can hear it squelling over the motor it would be easy to find........

Love your car, had one just like it in the early 70's, SS396, still have dreams about it.........damn......

No evidence of stator support spinning, and you are correct you would think you could see it. I may just send the converter for a look see.

Thanks for the compliment on the car, it is my pride and joy. =;

My 69 was almost the same as yours, same color, RS package, SS 396, replaced the 396 with a Don Hardy highly modified L88 - Lunati cam, replaced the turbo 400 with a 4-speed, Jardine headers, white vinyl roof, red interior( wasn't crazy about this), 5:14 gears. We would haul to area towns and street race for money and had quite an experience even gunplay, chains, knives, wild women and running from the law. Made good money for those days, had to, to feed my racing disease. I really miss that car......

Sprag was toast, probably my noise. Had it redone spragless and all is good now. No e.t loss in the 1/8 mile.

Bet your trans temp will be higher than normal......I have seen guys switch to the spragless and no change in the 1/8 but most see a big change in the 1/4 as much 2 to 3 mph loss and as much as 1/2 of a tenth but very constant....

Greg your car is heavy so it should work good for you... =;

Come on now Barry havent you seen the TSI ads in the National Dragster of how spragless are faster ;-)

In mine .. TSI and Coan Spragless dominate the all sprags I have tried. 3-4mph and 5 hundreths \:D/

David, it's because you have the right converter. I'd bet if you could take both converters and put in a sprag or diode without changing anything else you would pick up a little more in the 1/4. If the converter reaches the point that it wants to unlock a spragless will drag it down.

Barry, my times were dead on. No loss of e.t. went to the finals and broke out.

Temps stayed under 200 even when the rounds got real close together at the end of the night. So far I am happy with it.

I do agree, always been a sprag fan untill I started making power, once you waste one you dont go back =;
