Yesterday I added 2qts. Castrol Dex/Merc to my tranny before heading to the track, no I did not race it (i have a leak, output shaft area) and after an hour of driving my 3rd, sometimes 4th gear is extremely hard to get in and notchy at high speeds 60-70 mph. Also some of the other gears at times were locking me out. Before when my tranny was LOW on oil I never had this problem. At low speeds it goes into evry gear like normal.
Did I screw up my tranny by using the wrong fluid?
If I changed the fluid back to OEM GM P/N 88861800 would it restore my car to normal?
Is there a possibility I filled it too much? (I used the reverse hole with my car on ramps)
I have read all night about the oils users use, im looking to see if someone has had a similar issue.
no sure what the deal is with yours but my first gto had major 3rd gear syncro problems in both the transmissions i had in it. Hard to get in gear without rev matching, grinds, lockout ect.
Did you fill it until it ran out the reverse switch hole? If so you put too much in, you have to pre-measure the total amount when filling through there.
To reduce the level you can take out the fill plug (yes the one that says "Do Not Use") and let it run out until the fluid is at the bottom of the fill opening. If the car is level there will now be 3.8 qts in the trans. You can either leave it at that amount (many of us do) or add the additional .8 qt through the reverse hole.
ok so it was over filled, but after a long drive today i noticed it didnt want to go into 3rd at high revs. I still get to chirp my 3rd when upshifting, it just tries to lock me out of 3rd when down shifting
Now it's broken. Add supercharger, begin Chirpin4th. :gr_jest:
Are you giving the drivetrain any relief with a throttle blip to try and revmatch ? We can't read between the lines to understand if you actually know how to drive, but you can bet your synchros love you for taking a used car the prev owner surely beat upon and then giving it more.
I flush mine out every oil change, which is every 3000+/- miles, just to prevent this very scenario. If your fluid looks like this up in the reservoir, imagine what the slave cylinder must be like.
You're batting 1000. Rather than fix a leak you bandaid it to go racing. And you don't have any clue about preventative/regular maintenance. I'm I following the storyline accurately?
To answer your question, probably not if you're only having problems with 3rd. Still sounds like a synchro problem.
Flush your clutch system out, clean that reservoir out and swap out your rubber clutch line with a steel braided one. There have been quite a few threads on this and it sounds similar to the problems I was having getting into 3rd and 4th while on the throttle. That would be the easiest, cheapest fix to look at first in my opinion. When you get on it, your fluid and rubber clutch line heat up and won't allow the proper fluid through and that could cause your shifts to be very difficult... ( at least it did on my car ). Under normal driving my car was fine as well. By the looks at how dirty your reservoir and line are, Im sure your not getting the proper amount through there for a clean shift. Just my :cents:
Thanks for the advice xtaspeed05. You're rite it does only occur when the car gets warm. Im going to search how to fix this and I believe it should fix my problem.
I've been admonished to not actually post pics of tits, but everyone here except the hohos can imagine the most sumptuous, softest, most totally nice set you'd like wrapped around your Wang.
It's not like normal folks who know how to drive have this problemo, man. Truth be told, my GMM or the underlying trans doesn't have the best 3rd gate. This little hangup of OOOps missed 3rd resulted in 15-30 seconds of lost time when chasing Cyp and b4z. It took quite a while to catsup to dem.
update: so I flushed out all the nasty fluid, some of which felt like clay and my 3rd gear is way better after a day of driving on the new fluid. Thanks to all that helped.
