Definetly have some internal issues inside your tranny.
I woudln't drive it anymore to keep metal debris from trashing what you have left inside that is good.
I'd pull it and take the front pump out and start disassembling the broken parts may just fall into your hands so be careful.
Goodluck, Charles

mandatory upgrade, if they open it up can u take a pic
of the damage and post, man locking up like park while
the car is running, what did it do to the teeth, my wife did
that in the driveway but not enough to damage but the
noise, narly. :D

well its been cold i havent taken it out yet. i was hoping somebody might give me a direction as to where to look first. think im going to be a tranny man soon. lol

Sounds like the low/reverse clutch or center support sprag is locked. Good luck....
Put a glide in it and end your problems.

Sounds like the intermediate roller let go, this will jam up 2nd at times. Internal Failure.

go ahead and splurg and put you a JERICHO in the car ( fresh) you want have those problems anymore..for that matter you really will not need to use the clutch much...lol

ok guys i took my trans apart. front 2 drums were fine. when i went to take out the tail shaft i found broken parts. bearing? sprag? i dont know exctly what it is looks like a bearing to me but im no trans guy. somebody tell me what it is. there were 16 rollers in it. clutch roller bearing? still i dont see how that was making it lockup in 2nd and 3rd. isnt the back 1st and rev.?

That would be a sprag. I wouldn't reccomend you trying to rebuild it yourself since your not familar with them already,
I'd take it to a local tranny shop or someone more familar with rebuilding transmissions, I'm sure there's other damage there and just sticking another sprag in is just asking for trouble.
Things you can do while its being rebuilt would be flushing out the converter and trans cooler lines and the cooler it self BEFORE you go back with the rebuilt trans.
A spray can of brake clean or a can d natured alcohol will work good on the cooler and lines just spray the brake clean in the lines or pour the alcohol in and use a rubber tipped air nozzle and blow them out till the solvent runs clear out the other end.
Also you'll need to clean the valve body as well but the tranny shop should take care of that if you have it rebuilt.
Goodluck, Charles

You can get cooler flush in a can at some of the parts stores. Broken intermediate sprag.

it is the low reverse clutch roller. thanks for the info. im not going to take it to a shop it will be done here by me. i may not know what every peice is called but it doesnt look that complicated to me. old school low budget and i just cant afford to pay to have everything done for me. thanks guys

Go for it! :D

Transmissions are not that difficult, an automatic is easier than a standard in my opinion. Get a good tech manual if you don't have one. Just check all the planetaries, thrust bearings, bushings, pump, valve body and flush everything thuroughly, Be sure you get the pump haves aligned correctly when reassembling if you don't have a pump alignment band (or a really big hose clamp) you can use the trans case, by turning the pump over with no oring. Better to use the band but the case will work Ok.

Good Luck,

Bill :wink:

Sorry, I did mean the center support/low roller. If/when you can afford it, a powerglide is a better way to go for most. Take the time to take apart/clean out everything if you stay with the 350. It's a good idea to have the converter cut and cleaned. And you can't flush the cooler enough.

[kw89425]

yeah im thinking i may try to find a glide to build this winter. i use the car street and strip thats why i was trying to tough out the th350 but i want and brake and i wanna go fast...lol well as fast as i can with a pump gas motor anyway. thanks for the info guys

The glide will hurt the 60 ft. times but will be much more consistent.

[jmarksdragster]

Most cars will pick up ET with a glide. Unless the car is over 3800-4000lbs or has insufficient stall/gear it will pick up. A 3spd is worth a little in a Comp style car with a narrow RPM range, but those are high dollar light weight units as well.

ok. i dont think my camaro is that heavy. i just may have to make the change. thanks
