firefighter343 Posted June 25, 2012 Share Posted June 25, 2012 What's up everyone? My 72 Monte has a th350 and I have no foward or reverse, and it only starts in neutral. Once its running, I can drop the gear selector to any gear, I can hear the linkage moving. The gear indicator on the dash doesn't move tho. It stays in park. The car has sit for 5-6 years. Someone please help me with this problem. Also, when I insert the key into the ignition, I have to turn the key back toward me to start it, unlike most cars, where you turn the key foward. This is my first restoration, and I'd really like to get the car running before I start on the body work. I will post new pics soon. Quote Link to comment Share on other sites More sharing options...
black07ss Posted June 25, 2012 Share Posted June 25, 2012 Did you check the level of the transmission fluid? Quote Link to comment Share on other sites More sharing options...
Leghome Posted June 25, 2012 Share Posted June 25, 2012 My 72 started with the key turning backwards. It happened after I changed to a tilt steering column. I used the old switch but a tilt column uses a reverse mount switch causing the problem. Switched back tot he switch that came on the tilt column and that fixed it. I had to take the wiring harness and twist it 180 degrees from the was it was in the non tilt column. Quote Link to comment Share on other sites More sharing options...
firefighter343 Posted June 25, 2012 Author Share Posted June 25, 2012 I check the tranny fluid and its good. I'm not sure if it came with a tilt wheel, but the column that's in it is not a tilt wheel. Quote Link to comment Share on other sites More sharing options...
Grease Posted June 25, 2012 Share Posted June 25, 2012 DO you have a floor shift ? Possibly the cable has come off the shift shaft , or cable broken . Quote Link to comment Share on other sites More sharing options...
firefighter343 Posted June 25, 2012 Author Share Posted June 25, 2012 No, its a column shifter for now Quote Link to comment Share on other sites More sharing options...
firefighter343 Posted June 25, 2012 Author Share Posted June 25, 2012 What would cause it to only start in neutral? And could it be tied in with no moving gears? With the column shifter in park. I can hear a heavy click when I move it to reverse. But from reverse down thru the rest of the gears, its a really weak clicking sound.

firefighter343 Posted June 27, 2012 Author Share Posted June 27, 2012 Update: Took it to my mechanic today. We dropped the tranny, and took it apart. The clutches was burnt up. Hopefully we will have the tranny rebuilt and put back in by Thursday.. Quote Link to comment Share on other sites More sharing options...
bigtankjones Posted June 27, 2012 Share Posted June 27, 2012 What does it cost nowadays to rebuild a TH350? Quote Link to comment Share on other sites More sharing options...
firefighter343 Posted June 27, 2012 Author Share Posted June 27, 2012 I bought the rebuild kit and a new band for under 100 bucks, and my mechanic is charging me a 100 bucks to rebuild it. Which is dirt cheap because the local tranny shop wanted 900. Quote Link to comment Share on other sites More sharing options...
allchevy Posted June 27, 2012 Share Posted June 27, 2012 That's damn cheap! Hope it works out for you. Quote Link to comment Share on other sites More sharing options...
firefighter343 Posted June 27, 2012 Author Share Posted June 27, 2012 Yes it is, he is a very good mechanic, he builds open wheel modified cars for a living. I work at the local advance auto parts store now(body shop work got slow) and I give him good discounts on parts. So its he's way of paying me back.

cny first gen 71 Posted June 27, 2012 Share Posted June 27, 2012 Yup low reverse clutch pack got tore up probably due to a seal on the piston very commen on the th350. That is dirt cheep to rebuild it. As far as the other stuff im not sure but I would look in the ignition switch area on the lower coloum and nutral safty switch.

firefighter343 Posted June 29, 2012 Author Share Posted June 29, 2012 Update: we went to finish the rebuild today, got all the guts put back in and the paper gasket for the valve body was wrong. Going to get the right gasket in the am.. hopefully she will be ready for a test drive tomorrow around noon Quote Link to comment Share on other sites More sharing options...
firefighter343 Posted July 1, 2012 Author Share Posted July 1, 2012 Well we figured out what the problem was. The tranny in my Monte is not a turbo350, its a 350 lock up. I've got to order a shift kit for it and use the gaskets from it. I've never heard of a 350 lock up, is it a good tranny or should I look for something better?

montefrazer Posted July 1, 2012 Share Posted July 1, 2012 The lock up trans is just a Tubo 350 with a lock up converter. It was called the 350 C. http://en.wikipedia.org/wiki/Turbo-Hydramatic "Around 1980, a lock-up torque converter was introduced; this transmission was phased out in 1984 in GM passenger cars for the 700R4. Chevrolet/GMC trucks and vans used the THM350-C until 1986. The lock-up torque converter was deemed unpopular with transmission builders — B&M Racing once marketed a conversion kit for THM350-Cs during the early 1980s until the advent of high-stall lock-up torque converters when its overdrive counterpart (THM700R4/4L60) were modified. The standard TH350 is still very popular in drag racing." If you put it all together and wire it to work, you will get a little better highway MPG. Just remember to unlock it when you stop or it will stop the engine because there will be no converter slip. I had this tranny in an 82 Caprice.

firefighter343 Posted July 1, 2012 Author Share Posted July 1, 2012 Unlock it? How would I unlock it? Quote Link to comment Share on other sites More sharing options...
montefrazer Posted July 1, 2012 Share Posted July 1, 2012 You would need to wire power and a switch to the connections on the tranny. Then use it turn converter lock on and off. Quote Link to comment Share on other sites More sharing options...
Mike 57 Posted July 3, 2012 Share Posted July 3, 2012 It is normally unlocked. You have to apply power for it to go into lockup. They were not a very good system, I have seen a few take out the thrust bearing. I would not use it. Aftermarket torque converters are not readily available.
