I am going to post this into a few forums, but my car fits into multiple categories. This is a transmission forum, and that is where my problem lies. I was on a spirited drive the other night and ground 5th gear pretty bad. Yes, i was going way to fast, about 115 to be exact. as soon as i heard the grind i slowed down and then shifted into 5th, at about 90 mph. went into gear fine. got to my destination and parked the car fine, thinking that i had just been an idiot and tomorrow nothing bad would happen. Well, it did. woke up in the morning to no reverse. I have had minor issues in the past where it took me a few tries to get it into reverse, but it always went. well now it simply wont. I have tried putting it in while moving backward, revving and putting it in, going quickly from 4th to reverse(not while going forward), but to no avail. it is really shitty as i was just about to tear apart my motor for a turbo build. My question is do you think that it is a specific tranny problem that can be fixed, or would i be better off replacing the whole trannny( i have a gsr swapped ek with gsr tranny) with a LSD? budget really isn't a concern as this car is my passion, but it would really suck to buy a whole new tranny if mine was a simple fix. I know this was alot to read, but i wanted to get as much info out there as possible. if you have any experience or input i would forever be in you debt. worst part about it is that i haven't driven my baby in a week. SOOOOOO SHITTY.

 

replaced fluid today....still no reverse. any ideas on where to look next?

 

Replace the 5-Reverse synchro set and 5th gear, if needed. The two gears share the same synchro hub and sleeve. If you damage the 5th gear side badly enough, it can prevent you from getting into reverse.

yeah since you ground it pretty bad. you more than likely developed bad burrs on the end the 5th gear sleeve synchro teeth from that grind. basically they are catching on the hub splines and won't slide up and to the reverse end. the transmission is gonna have to be dropped and opened up.
