what transmission did v6s come with?

[onyxxtreme]

my last cutlass had the base 307 with the 200.
Honestly, I haven't checked my current car. I figured with a base 231 and 3spd, it would have been the 200 also. Guess I need to actually check it now.

Do the G-body's even use different RPO codes for the different transmissions that were put in these cars? -Or did they just slap whatever trans they could find, in there? (Like how they did with the various aluminum parts?)

yes, GM had a different code for each part that was placed in each car. The sticker thats on the decklid with all the different numbers and letters is the rpo code sticker. ( im sure you already knew that) That should tell you what your car come out with factory. Ive looked for a decoder for this tag but can't find one but there is a post on here somewere that will brake down the vin. Usually if you have the build sheet, which is usually found in the rear seat somewere, will tell you what was put in your car in plain english with the code.

If the various aluminum parts your talking about are like aluminum Brake drums, those were dependent on how weak the car was :lol: my 79 Monte that i had, come with a 305 and 350 transmission. the rear end was geared so low, 2.29 i think, and the car was so light, (no options but ac) it didnt need a heavy duty brake system. The rear decklid was even aluminum. It had 14 inch turbine wheels also. Factory aluminum wheels. (Or so i was told this by the chevy dealer that sold it in the town i was living in at the time). It was a perfect canidate for a 350 swap, thats for sure. But i traded it before i could get that far.

My '79 Century V6 wagon had a th200, it never gave any problems over 200k (kilometers) even though it undertook plenty of towing duties during my ownership. It had a transmission cooler fitted by a PO which probably helped prolong its life, refraining from drag strip style driving no doubt also helped.

My '83 Bonnewagon came with a Buick 3.8 and a T-350-C. I got it at almost 100K and after a filter/fluid change it just soldiered right on. Dirtiest filter I've ever seen too. I then used it behind a 301 in my '81 Malibu wagon for several years. After I was done with it I donated it to a circle track racer and as far as I know it's still working.

upon further reflection, I am now convinced my 1980 had a 250 and not a 350 as I had always thought.

1. On snowy days or wet pavement my car would NOT stop with the foot all the way down on the break. The real wheels still would slowly spin. Even pumping the brakes would not work. It was kind of like having the emergency brake on and pressing the accelerator. If I had this problem i am reading about in this thread with the car not coming out of second gear that might explain why that would happen. On dry pavement the friction of the pavement would keep this problem in check.

2. On hard deceleration or fast stops the car would always stall out. ALWAYS. So i adopted a "pumping" action to my hard stops, which I seem to have carried over into my driving now, 15 years later! I guess since I learned to drive on my Cutlass this habit stuck with me.

3. The engine and carb were all perfectly tuned by professional who knew carbs and the brakes were in top shape. That V6 was running so smooth I did not even know when it was running and often times would turn the key and grind my starter. We spend hundreds of dollars trying to get the car to stop stalling and acting up on slippery surfaces till the day the V6 threw its timing chain and I had to put a 350/th350 in the car. I have no had a single issue with stalling or the transmission staying in another gear. Why? I think because I upgraded to a REAL the350 from a junk yard and had it rebuilt.

Amazing what I can learn on this site just when I think I know everythign about my Cutlass!

My '79 Cutlass had a TH200 too that went 160K miles with no problems. My grandpa bought it new so I have the full history and he said it never gave him any problems. I guess they weren't all bad. I only replaced it because I wanted to regear and upgrade to an overdrive. BTW, it has a 305 -- not a V6. I just wanted to point out that the TH200 wasn't all that bad in spite of what everyone seems to think.

My dad's '82 El Camino had a TH250 behind it's 3.8 (Buick). Not sure if it was original but I suspect it was.

I agree. I think that left stock the th200 would and did last at least as well as the engines they were put behind. The 1980 3.8 v6 had 110 hp for goodness sakes! I think my Oral B toothbrush's motor has more torque too!

My first '86 Grand Prix had the Buick 3.8-lter V6 and the POS TH-200 (and it had no reverse gear when I bought it).

i made a post on here earlier for saying that the 200 was a 4 speed transmission. sorry for the confusion guys. But i had a 87 cutty that had the 200 metric in it. I drove it for about 300 miles and parked it for a couple hours. when i went back to start the car, it had "jumped" and made a slight clunk sound. well i checked it out and found nothing wrong underneath. started it up just fine and let it sit for a minute, put it thru the gears and no problems so i put it back in park. sat for about 2 or 3 minuts before i headed back out and all of a sudden it started bellowing smoke from underneath!!! :shock: I thought the damn thing caught fire!!!. Come to find out, there was a plastic pump cover that had melted and blew out. how in the hell it did that was beyond me but i sold the car not to long after that happened.
