    TH350c Slipping

    Very insightful Rob! I honestly didn't even think they still produced Dextron III! I met Andy Rooney (60 minutes) one time and I brought him a hat from the company I was working for. He examined it front and back, which I assumed he was looking for a snap back or something and then I said "It's...

    TH350c Slipping

    I have wondered the same thing! Along with that train of thought, whatever they were using 40 years ago for adhesives and friction materials are probably completely different from what is being used today? So modern parts=modern fluids ...? All that being said, I'm assuming there are still...

    TH350c Slipping

    Hmmm...it was a natural steel plate...however I can 100% guarantee someone other than the factory was in there before I was as there were aftermarket gaskets.. I was looking on the Transgo website and their shiftkit mentioned something about keeping the 350c separator plate and drilling it out...

    TH350c Slipping

    Hey Matt, SirRobyn0 had a great idea to run this one by you as I had it posted in another thread I had going... So after thinking about this a little more...I did "modify" 3 things when I put the trans back together (1) hardened outer race (2) 5 clutch piston (and I did indeed put in the 5...

    Received Sir! Thanks much for your direction! I have another thread open that it would probably be more appropriate to send a shout out in.

    White smoke troubleshooting

    I'll take any help I can get!! So after thinking about this a little more...I did "modify" 3 things when I put the trans back together (1) hardened outer race (2) 5 clutch piston (and I did indeed put in the 5 clutches, haha) and (3) dual feed by leaving off seal on direct, ring off pump and...

    White smoke troubleshooting

    Thanks Rob! I did the block test and it was negative so I think your gut is on to something! To answer your questions: How much run time you have on the engine? -I broke in the cam and have probably driven it for about 5-10 miles before the trans started slipping pretty bad You did say it was...

    White smoke troubleshooting

    If the block method comes up negative that is going to be my route...the block test is going to cost me $8 for the testing solution..

    White smoke troubleshooting

    Here is a video link...it seems as though the smoke starts at about 1 minute in...smells like it running rich BTW...also stepping back and listening to the video it almost sounds like a rod knocking (I though that was the smog pump noise)...

    White smoke troubleshooting

    Thanks Rob! I will grab a video once the rain stops out here...at the risk of exposing my inexperience, I had never seen/used a block tester before. It looks like I can borrow one from the local Autozone and get some fluid for it. Thanks again!

    White smoke troubleshooting

    The hits keep on comin'! Quick history is that the engine was rebuilt by someone I don't have a lot of faith in...I have basically broke in the cam and put about 5-10 miles on the truck and started having all kinds of other issues (the truck sat for 5 years)... One issue from the beginning...

    TH350c Slipping

    Ok...disclaimer- I haven't got around to a full blown road test yet, however I removed the spacer shims from the torque convertor and I took it for a spin and low and behold the temp at the pan was 114deg F... Ironically when I took out the shims on the torque convertor, my starter started...

    TH350c Slipping

    Going through stuff, it looks like I picked it up at AutoZone so I'm sure it's not a high end unit.. You think I got a bad one? I bought it about 6 months ago but haven't put it into use until now...is there any way to troubleshoot the tranny to isolate the problem to the TC?

    TH350c Slipping

    Hi Matt, I actually did both, and installed a hardened sprag as well...I figured pulling the trans and reinstalling it was too much work not to do as much as I (practically) could with it on the bench.. If the convertor doesn't lock I can live with it...for a while anyways... but I would...

    TH350c Slipping

    I pulled off the lower bellhousing and it doesn't look like there is some massive leak..the TC is dry and it looks like it just leaking from the bolts a little bit..I have seen more than a few th350's leaking for more that function just fine.. One thing I did do when I installed it was to shim...

    TH350c Slipping

    Valvoline multi vehicle stuff...so I looked underneath and there appears to be some drops of fluid coming out from the bellhousing...Let me pull it off and see if I can tell where it's leaking from. Its a lockup convertor, do you think it might have something to do with the o-ring on the end of...

    TH350c Slipping

    Hey all, I was finally able to get everything put back together in my 1981 Suburban and my hope was to take it down to get a smog check and registered...however on my way back from getting gas (a painful $5.79 per gal btw) the trans was slipping something fierce. It's a fresh rebuild, I did the...

    TH350 Rebuild Questions

    Ok...yet another twist... I went to stomp down on the ebrake and it doesn't even get to the first click... I rebuilt the brakes/master cylinder while it was in the driveway and adjusted the drums to what I thought was good...I have to say I was impressed at how well it stopped! However, is it...

    TH350 Rebuild Questions

    So I looked at the modulator, vacuum line and everything in between it and all good. Hooked it back up and tried it out...seemed to do fine up and down the driveway and street so I'm thinking it only happens when the tranny gets warm...if the cooler lines are backwards would that have anything...

    TH350 Rebuild Questions

    So after doing some more reading, it seems if the vacuum modulator diaphram is bad it will suck tranny fluid and you will get smelly white exhaust. That is actually something I have happening as well which I thought was odd with a rebuilt engine but given the truck sat for 5 years I thought is...

    TH350 Rebuild Questions

    After racking my brain and going through the links and notes I have, I did do the dual feed mod as recommend but I really don't remember tapping and plugging the reverse feed hole... Would that give me the behavior I'm experiencing?

    TH350 Rebuild Questions

    It has not...long story short is I had all of the components rebuilt and sitting in the garage to go back in and then I ended up buying a house that needed a lot of work... priorities changed... I agree with the fact I shouldn't be driving it all that much...it would be cheaper for me to swap...

    TH350 Rebuild Questions

    Well...reporting back after I took her on the maiden voyage to fill up the gas tank and hopes for a smog check... Seemed to reverse out of the driveway fine and headed on down the road. I went about 2 miles to hopefully fill up at a Costco and saw the line and said I'll pay the extra twenty...

    Horns

    I used a multi meter to test for power...my understanding is that if the orange in the harness was hot then if you jumped it over to the green you should get music? I'm getting confused a bit now...and given it's only 3 contacts that might mean I'm in trouble now, haha!
