Pontiac - GTO :: 1970 - Unpainted Transmission Is Original?
Jun 8, 2011
I have a 1970 Pontiac GTO that i am restoring. It has the original matching numbers YS Code 400 HO engine. When I got it a few months back, it sounded pretty rough. We removed a valve cover and found a bent push rod. At that point we decided a complete rebuild was in order. We removed the motor and transmission from the car. I'm want to know if the transmission is original to the car but I don't know how to check the numbers for that. However, I could have found a clue. When we cleaned the motor and transmission I found the motor had been painted twice - the factory color with another blue over the top of it; the transmission had never been painted! Did GM ever produce cars and send them out with unpainted transmissions or has it just been replaced at some point?

I have a 1970 f250 with a factory 390 (vin verified) and a C6, I believe the transmission was rebuilt but have no way to verify. It works fine while cold and mildly warm. Once heat soaked it is very slow to shift (going from neutral to reverse can take almost 30 sec) and leaks profusely from the front. I can not tell exactly where the leak is. Could this be a case of just having too much fluid or is there a more serious concern? The dipstick does read high but level ground in my area is hard to come by so the accuracy can be questioned. If it does have to much fluid, do I just drain the pan, re-install and let it run till hot and replace fluid as needed or should I drain and replace with 3 qrts prior to starting?

Early 70's Ford Truck w/Dana 20 Xfer case
The problem is that when I put the truck in 4W Low, it will sometimes slip out of gear into 4W Neutral. It happens more often when climbing hills than driving on level ground. It hasn't ever slipped out of 4W High. It is drivable the way it is, but it's annoying. If there were an easy fix I'd do it. If I have to remove the xfer case, that seems like a big job, so probably not. What do you think?
The manual suggests these four as possible reasons
Shifting poppet spring weak.
Bearing broken or worn.
Shifting fork bent.
Improper control rod adjustment.
Which is the most likely problem? What is the "poppet" for and where is it located? Can anything be done to diagnose or fix this problem w/out removing the xfer case from the vehicle? What about the control rod? Can it be adjusted with the xfer case installed? If so, where is that adjusted?

Purchased this car almost two years ago and it would typically start up no problems after sitting overnight or for a few hours. However, after running the car and then say turning it off to pump gas or just for a short stop, it never starts up right away. Just this week I had it taken to a friends repair shop (yeah, I know) and was told they moved/adjust distributor caps and checked carb and that they saw no other problems and they had it starting it up every time. They had suggested that what I needed to do was run the old gas (its only been sitting about 3 months) and keep running premium until we are certain that nothing remains in the tank except new gas, but assured me that the car was good to go and they sent me on my way.
Now, they didn't charge me, which is great, but I got what I "paid" for when I took the car out for about a 45 minute cruise, stopped for gas, and without fail the dang thing wouldn't start. A lovely citizen at the gas station raised the hood, fiddled with the carb, as he didn't think it was a battery issue, and was able to get the car going and get me home, but again, car wouldn't start about 20 minutes later. Hours later, out of curiosity, attempted and car started just fine.

I've begun restoring my grandpas 1970 Chevy c/10 but I can't seem to get the brake drums to budge. I tried several cans of lubricant and even beat on one with a sledge hammer till the outside broke off. But the front face of the drum still won't come off. How to remove them?

My 1970 chevy c10 pickup is a 350 with automatic transmission 2wd. It doesn't get driven frequently and when I do the first time I put it into gear, fwd or reverse, it is slow to engage. Shortly after it has warmed up however, this problem goes away. What this sounds like?

I went to drive my 1970 Nova today and after driving it for about 15 seconds it seemed to stick in second gear. I cannot get it to go into neutral to be able to put it into any other gear including reverse. The shifter is on the floor. I have no clue what is going on- If it's something with the linkage between the shifter and the transmission or something with the clutch. It has never acted this way before and gave no indication that a problem was on the horizon.

It has a floor shifter for the xfer case with 2wd, 4wd-H,and 4wd-L, and Neutral positions. It works fine in the 2wd and the 4wd-H positions. The problem is it sometimes slips out of 4wd-L position into 4wd-Neutral, which I have just lived with, but it is annoying. I think I heard this is a known problem with these 1970's Ford xfer cases, and the fix involves removing the xfer case and replacing a part.

I drive a 1970 Jeep Cj5 which I've dubbed, "The Red Bucket" because, well, it's red (duh) and because of its complete lack of doors, top, roll cage, and a folded down windshield. Anyway, I drove it to work about 2 days ago. Started fine, drove fine, no problems. When I came back from work it started fine. As I drove down the parking garage, the engine, a Buick Dauntless v6, just stopped. it didn't really even sputter either, just stopped, leaving me rolling down the garage with no power steering.
Now, at this point, I just though I had flooded it, happens all the time so I figured, "Hey, no big deal." If I've flooded it good, I normally only have to wait about 10 minutes till it springs back to life. However, after 10 minutes, 20 minutes, and 30 minutes, I was forced to call home to get a ride. Now I am a little worried, but I shrug it off thinking I have just flooded it really, really, really, bad. I drive up the next day to try and start it again, but only to find it in the same condition as the day before, starter turning, lights working, but still nothing.
Now, my knowledge of cars really doesn't go any farther than YouTube. I'd consider myself a "car guy," but I am no mechanic. That being said, based on my knowledge of distributor caps, my current hypothesis is that for whatever reason my distributor cap is not functioning. To go into more detail, there is starter noise, but no vibration or noise from pistons beginning to move and fire. Also, roll starting did not work and I am not out of gas, good thoughts though.

Well I have to make a long story short, suffice it to say this is a bit embarrassing, but I need an answer: I removed the 440-t4 transmission from my daughter's 1987 Pontiac Bonneville and had it rebuilt. After I replaced the unit I discovered I left off (and lost) the TV link and cable. I (miraculously)found the link and the cable, and I am wondering if I can replace the link without having to remove the side cover of the transmission, and what I can do to avoid dropping the TV link rod down into the trans while I am trying to reattach it to the linkage arm inside the trans thru the little TV link hole on the top of the trans.

My 1970 Nova has a very stiff clutch pedal. Is it possible to adjust the tension on it? It's getting to the point where it makes my foot sore to drive the thing- very annoying. It has a 3 speed on the floor gear-shift.

I have a 91 pontiac Grand Prix with a 3.1 and the car has NO leaks, however, I have noticed that the transmission fluid level go down and the engine oil goes up. My conclusion is that some how the tranny fluid is crossing over to the engine, is this possible? and if it is, how or where?
NOTE: my car has a tranny cooling line to the radiator but no engine oil cooling lines and the colant is clean. how is it possible?

I have a 2001 pontiac grand am se 4cyl with an automatic transmission and I've been having issues with my transmission, about a month ago the transmission started shifting hard then just went out so i took it to a transmission repair shop and the tech said that it was the pulling clutches and i told him to completely rebuilt the transmission including new electronics and torque converter and he did i got it back and it drove fine for that day then stared doing the same thing my transmission slams into gears and I don't know what the problem is sometimes ill be going down the road and the transmission slams and then the trac light comes on for a little bit then goes back out??? also some days i can drive it a mile or 2 before it starts slamming into gear.. what this could be causing it to slam i would think it couldn't poss be the transmission as everything has been replaced? could something else be causing it to slam into gear..

My sister's Grand Am has been having a shift flutter issue (between third and fourth, around 40 mph it would shift rapidly back and forth until you either forced a downshift or reached 50-55 mph) for a while now. I read a lot about it online, and all signs and the experiences of others pointed to a bad shift solenoid or pressure control solenoid. I wanted to correct the issue before it caused any damage to the transmission. I removed the transmission from the car and replaced both shift solenoids, the torque converter clutch solenoid, the pressure control solenoid, and the manifold pressure switch with new ACDelco parts. I figured I may as well replace them all while the trans was apart. I also replaced the filter and fluid, of course. I got everything back together, and now the transmission slips in reverse and overdrive no longer works. Fluid level is full according to the method of pulling the level check fill plug while hot, idling in park. I used Valvoline Maxlife fluid, which meets Dexron VI specs according to the product label. I have double and triple checked everything and can't even fathom what I could have done to cause these new symptoms to crop up.

I have a 2001 Montana with 140,000 miles on it. I bought it used five years ago. The transmission is going out. The shop did a scan and found the torque converter clutch is sticking on. What this is? Should I make the repairs or ditch the van?
Good points: four new tires in December 2013; body is great; and minor maintenance repairs.
Bad points: the air conditioning is broken and the heat is forever terrible.
The van is currently at my regular shop and they do not do transmissions so I do not have an estimate or more information about the problem.

I have a 2000 Malibu, with the original radio, and I'd like to hook up my MP3 player to it. I know that I could get something to hook up to the MP3 player that would broadcast over an unused FM frequency and play it that way. But I've been in other people's cars who did that, and it lost a lot of quality that way. Any way for me to wire something up to the radio that would let me plug my MP3 into it, either with a USB cable, or even a plug like the plug on my ear buds? If so, how would I do it?
