Ok, i got a 305tbi with a 700r4 trans, when i bought the car it would hang in 2-3 rd gear some so i knew the trans had some wear on it. I replaced the filter, fluid, gasket. there was a good amount of silver sludge "metal" on the mag so im sure the trans was beat on pretty bad. Anyways i noticed that sometimes the trans wouldnt lock up when i put it into OD, sometimes it would sometimes it wouldnt. I tried getting it to lock, but pushing the gas pedel down some it would lock, then it would unlock. Well on my way to work this morning 50mile drive, it locked up i was like sweet!! I come to a stop here at work take off, first gear is hanging and hanging then abotu 5grand it slyly slips into second, i push on the gas about half pedel it reves up, so like i have to rev it really high then it will finaly shift, my question is, is this a selonoid or am i just gonna have to replace the tranny, i have a back up tranny outa another camaro, just dont know its condition.

The solenoid only controls the torque converter lock up. If it is slipping at all, and the fluid level is correct, the trans is done.

 

hmmm, it dont slip in first at all, but im thinking the SOB is totaly done. the guy i bought the car off of, was such a meth dealer, crackhead so im not supprized this problem has came upon me. I got a spare transmission to put in, outa a 92 camaro, that should bolt right up will i need to change anything else?? or will it swap perfect! ?

 

If this happened all at once, then the governor gear most likely broke or stripped.

 

hmm well today i found a 91 camaro z28 tpi, for 1k its awesome shape better then mine,but has no t-tops the kicker is its only 1000$ and the bastard has a supercharger, think im gonna pick up on that, and make this one a part car, along with my other camaro,!!

 

before you do anything try this, get the car at a roll in 3rd or second 5-10 MPH drop in to first while at WOT for a second and then go through the gears that should solve the issue - it some sort of debris blocking a passage way and doing what I said will accelerate the fluid quick enough to dislodge anything. An yes I have done this on customer cars and my own car a year ago and haven't had the situation return yet, and the worst that can happen is nothing if the tranny is toasted or you'll be comfortably driving around in no time flat

 

hmm i will try that today once i get in y car. cuz it did happen when i was going under a bridge i reved the car up, then it started acting this way.. would this work neven though if i mash it rolling about 15 mph, in second the rpms will just keep going past 6 grand?

if that dont work thou, im just gonna drive the bastard like i stole it on the way home "50miles drive" and i break it i break it or fix it lol

 

to really get it to move the passages open while it is in first and stomped are your best bet at about a 10-15 MPH roll. 1.Get the car to 10-15 MPH in 2nd or 3rd 2. drop it into 1st while simultaneously going WOT 3. Release the accelerator almost immediately - What you are doing is trying to get all the fluid in the tranny to thrash it's way through to sort of "shock" the system

 

Just tried that and it dont even wana shift on the shifter no more, and it about blew my motor , i beat the crap outa it on the way home, no luck, gonna do what i shouldnt, gonna get some of that trans trick shift stuff and slap that in to stop the slippin

 

if It stoppe shifting even more that a good indicator that there is a lot of debris in the pan so you may have to fall back on your orig plan. BTW when you put into first and punch it you need to let right back up off the throttle. Sorry to hear that I've saved a lot of those trannys from unneccessary rebuilds that way.

 

To follow up on the thread, shortly after the tranny crapped out, only had first gear
