i have a 67 buick skylark with the 300 cid v8 with a 2 bbl and a super turbine 300 two speed automatic transmission and when i am driving when it shifts from 1st to second it makes a screaming noise almost as if a bearing is smoked and it screams steady when i hit 70 mph and what i was wondering is if it were a bearing that was going and what can i do to remedy this issue short of a complete rebuild also i removed the dust cover from the torqe converter because it was tweaked and was rubbing on the flywheel plz help a fellow classic buick enthusiast
If it is the trans,it might be a dirty,really clogged filter.Chance that and if that does not fix it,then your problem is most likely a wheel bearing.BrunoD.
The trans in my 79 Eldo started squeaking under power. I trashed the TH325, put in a switch pitch TH425, squeal gone. Bruce Roe
thank you to all that posted i really appreciate the help i dropped the pan and there was no metal shavings no discoloratian and i was good on my gluid leval and as for the tranny filter it was clean so im still at a loss as to what the heck to do with it i was thinking i may just end up getting a 2004r tranny and putting in it any thoughts on that?
search around on the forum using the search function. There are people who have done the st300 to 200r4 swap and it was a really good swap. keep in mind if you are not wanting to change the rear end ratio then you might aas well just use a th350 because not much need for an overdrive gear with the stock gearing.
Check the bearing in the tailshaft housing, it supports the outer diameter of the driveshaft's yoke. If it's wiped out it can make all kinds of weird noises when the transmission shifts. Devon
If that bushing is shot it will also cause a vibration and will leak because the yoke will move around enough to ruin the rear seal. And if you happen to have a plugged up filter, good luck finding a new one. I checked everywhere I know of and couldn't find one anywhere. Just a thought. These transmissions have been out of service for so long that parts have become obsolete. Unless you need an overdrive, the TH350 would be the easiest and cheapest bolt in swap but you'll have to get one with the BOP housing. A dedicated Chevy trans won't work but GM did build some in the early 70's with the universal pattern that will fit them all.
I've had speedo cables that squealed loudly at certain speeds but that was usually in cold weather. Might be worth a try disconnecting it at the trans. Easy to do. 2nd the motion to forgo the 200R4 if you keep the stock gears. You'll rarely get it into 4th if you have 2 series rear gears. The engien just won't pull them that well at lower speeds. A t350 will perk up the performance noticably with the better gearing and may add a little MPG around town because the car will be able to pull out easier. If you drive the car on the highway alot and put on greater than 5K a year the OD trans may be worth it but if you don't put alot of miles on the car then it is alot of $$$$ to pick up a few mpg and the t350 will be a better choice. Pretty much a direct swap for the t350.
The 2004R is a much better choice than the TH350. lower first gear, overdrive, lockup converter and it's the same amount of work to install either transmission. His 300 and 2.93 gears will pull overdrive just fine.
Bill, you must have ignored my second paragraph above. Nobody said the 200 would be a bad choice. Just not a good one. It all depends on how much you want to spend to save some money on gas. If you drive alot it may be worth it. If you don't drive much it would be a big waste of $$$$. Figure on even a decent 200 being $1000+ while a great 350 would be wayyy under that. That's alot of $$$$ for minimal savings. Again this all depends on how many miles you put on. Even if you went with a used trans to save money I'd put my trust in a used 350 way before the 200. The increased off the line gain from the change from a 350 to 200-4R would be minimal. 2.52 to 2.74 but either one would be like a rocket compared to the 1.8ish first of the ST300. The only thing for sure as far as the 200 being a direct bolt-in is the driveshaft wouldn't have to be changed. After that things get a little shakey, especially compared to the 350 which is a direct bolt-in. I've seen way too many people, on this board and in my actual experiences, install OD transmissions just because "they have to have an OD" and then when it is all done they rarely ever hit the highway putting on barely a few thousand miles a year. I think in this situation either trans is a winning plan, just one's gonna cost more.
My actual experience has been different from your's apparently. All my O/D conversions have been succesful and some had 2 series gears. In all cases, I've gained mileage, even in city /urban driving. The locking converter does wonders for driveline (converter) slippage at low speeds. I leave the selector in the direct gear position below 40. Even my 427 Biscayne wagon picked up 1.5 MPG in city /urban driving, 5 MPG on the highway. A friend of mine just did the conversion on a '65 Skylark. Day and night difference all the way around. He now enjoys the car so much that he is driving it daily. (it sat for years because he hated driving it) The low gear difference is about 10 percent. Ten percent is ten percent, nothing to sneeze at. Many would love to have 10 percent more power and as far as launch ability, in this case it's free. (free performance increases are always worth it) I don't understand what you mean by "shakey". In the case of a 67 Skylark, moving the cross member back 6 inches involves the drilling of 4 holes. Both transmissions will require a throttle cable to be attached to the bell crank so that is a wash. Torque converter lockup can be as simple as a toggle switch, no biggie. 2004R's are far more plentiful these days than BOP TH350's, at least around here. I feel the TH350 would be a waste of time to fool with when there are better alternatives.
