Transmission, disengages, wont go in reverse...

[94"che-rolet"z34]

heres the deal....

Alright, history first....

94, lumina Z34, 4t60e trans, has only 89k miles. never ever EVER had an issue with the car. have done ALL preventative maintenance. driven normally, only show off occasionally when that rice burner just has to be shown up... it has never given me a single problem before, not a thing.

now, as i was leaving my house, i get a few hundred feet, hit about 35 mph and all of a sudden, i lose the trans and the engine revs up. i LOST the trans altogether. pull over, try reverse, nothing, but, put it back into drive, and it will go until it hits 20, lose the trans, revs up, let it drop back down, and it will shudder/jolt and eventually re-engage. but, will not leave first. and, i remind you, i take care of this care as if it were my child. i keep up on all maintenance and drive her nicely. like i said, i RARELY push her. and she jas never ever been pushed ot her limits be me. and, before this, no indication WHATSOEVER! no noise, missed shifts, slipping, juloting, shuddering, NOTHING! just outta the blue, i have a transmission issue.

I NEED YOUR INPUT! I am NOT car illiterate, this has just got me stumped, and, i just cant think of exactly what it could be.

basically, im looking for someone with EXPERIENCE with this issue, either have had this happen to them(and if so, i feel sorry for you) or have had to fix it or known someone that has.

so, PLEASE, give me your advice.

thanx for the advice, but it doesnt sound like my problem. there is a definant rattling noise coming from the transmission. someone told me that theres a knuckle that could come loose and that it may be that. but, would that not create the loss of all gears? considering all ive got is 1st... i seriously dont know. this has got me stumped here. I personally think that it seems like a clutchpack fragmented, but, i dont know... so, once again, i ask your assistance.

first off, check your fluid level. i know it seems basic, but its often overlooked and if low, could cause issues.

if the tranny has never been built, then you have done very well being its now 11 years old. i have seen 4t60e's that are 4 years old and smoked beyond recognition. what i would do is take it to a reputable tranny shop and get them to have a look at it.

the fluid level is fine. but, it is now brown and smells burnt... but, ive got a new trans lined up and im going to be installing it starting tomorrow. thanx for your reply, i really do appreciate it.
