Unhappy 350tranny. no reverse.

Hiya everyone. i was reading thru all the threads earlier. i found alot of helpful info. but i jus want more reassurance i guess. hehe

I have a 82' k5 Blazer. and i offroad alot. i try to keep my tranny fluid topped off . but recently during a little expedition. i noticed my reverse gear took about a second to slip into gear. i didn't think much of it atm. i thought maybe my tranny fluid was low. So. i kept on crawling (i shouldn't have!!!!!)..... after a few more obstacles. i noticed the shifting delay into reverse was gettin longer. so i called it quits finally . i didn't have any tranny fluid on me.
I get home put some tranny fluid in and i park it. let it sit. the next day... i go outside and put it into reverse to get out of my parking spot. It doesn't go into reverse for like 5 , 6 seconds, so i give it a little gas, and there was a kind of a grinding noise and a huge jerk. then Poof! my reverse gear wont work anymore. its my everyday driver, so i go places with it still, so when i manual shift down the gears. D to L2 theres that engine braking or whatever, but from L2 to L1, theres none. wierd . Oh yah. and when i put tranny fluid it. it goes down reaaally slooowwww....

Rebuild needed ya think? hehe. thanks , any info will be helpful. im new to this tranny stuff.

Btw, its an automatic. lol

it's time for a rebuild, if it's a th350 ( the trans pan square with one corner cut off ) the reverse and low clutch use the same clutch pack. you probably notice that it slips in low too

========== the tranny will not slip in low gear while in "D" or in manual low if the roller clutch is working correctly.

First gear in the "D" shifter position is created with the roller clutch 'holding' in the center support and the forward clutch applied. The forward clutch is the drum with the input shaft.

The lack of 'engine braking in manual low gear does indicate the low/reverse clutch pack is NOT functioning correctly.

The low / reverse clutch is applied 'only ' in manual low(L1) or reverse.

I hope this helps

I gotta sign this too?

What about the problem with my fluid going down slowly? a friend of mine said something about a vent being clogged. Are they easy to replace?

Thanks for all your info. 8D

Sonks!
