Broken Transmission

[edthemanjp]

I know something broke and I have my guess but I'm going to put this out here and see what you guys think. This shouldn't have happened but I guess stuff is going to break and especially when the power is increased but this is an odd one.

My Transmission is a route 6 cross with 2 & 3 gears changed, I'm running Red line heavy duty shock proof gear oil, street tires 255 X17, outside temperature around 50, my operating temperature 68 Celsius mine usually runs at that temp, boosted 1.44, and I was on an on ramp entering a highway.

How it happened: Entering ramp to do a test run 1st gear shifted at 7898 rpm into 2nd, full throttle till 7352 rpm and noise and obvious drive issues. Noise is there when clutch is out alls quiet when clutch is pressed. Let clutch out noise and doesn’t seem to engage and then jerk it engages for an instant. Couldn’t drive had to be towed home.

I thought it was something with my clutch nope clutch is fine put transmission in gear turn output shaft and definite catching going on inside. I think I know what it is but I want to hear what other people have to say before I say anything.

Noise is clang clang clang clang sounds to be in sequence with rotation of flywheel.

I always data log thats how I know exactly when it happened

Pictures to confirm more to follow after I get the transfer case off its stuck like glue and I have all 10 bolts out

Here it is now does anybody know where I can get a route 6 replacement gear set and how much. I just can't replace the broken 1, all have to be replaced.

If your trans is the same as my R33's, I can probably hook you up from the dealer. But, I'll need the part number for the assembly that you'll need.

Thanks, I actually have my broken trans a spare trans and a spare set of gears, you always want to be prepared. The spare trans is an r33 trans with bolt holes already tapped for push type slave cylinder. I currently have the spare trans apart checking to make sure everything works good, checking syncros. If I need parts I will definitely hit you up Thanks

Took a spare R33 GTR transmission I had apart examined it no broken teeth, Synchros looked okay, the transfer case had gear oil (shockproof) so I cleaned it set it aside and used my original one. Put the transmission back together wrestled with it for about 4 hours, the bell housing and input shaft were giving a hard time but once transmission up slid right in maybe 15 seconds of rocking it. Drove for a short bit and put her back in garage its raining.

Alls good
