I pulled my T5Z to install a new clutch and drained the non-sythetic fluid. No grinding going into 5th gear before I pulled it. Reinstalled and re-filled with synthetic fluid and it grinds going into fifth. I'm going to drain again this winter and go back to non-syn. It must have something to do with 5th gear being a brass syncro cone instead of the lined one in 1st thru 4th. Maybe synthetic fluid is too slippery for the cone to engage properly?Yes, I purchased the Kit from LMR and the kit came with new cross member bushings, trans mount, SVE short throw, and 3 qt’s of the RP. In their review video they recommended the RP. So tomorrow when I go buy new fluid, what brand do you recommend? Just any non synthetic type 3 atf?
I think you’re correct because mine shifts the exact same way. Thanks.I pulled my T5Z to install a new clutch and drained the non-sythetic fluid. No grinding going into 5th gear before I pulled it.

Almost like the syncro cone is slipping and it takes a few seconds for the gear speed to match so the syncro works right.
I think all of you have made up my mind of going T5 or Tremec 600.....I pulled my T5Z to install a new clutch and drained the non-sythetic fluid. No grinding going into 5th gear before I pulled it.

I run the Z spec in my '89. I tagged the 5th gear synchro the first time I drove it down the 1/4 mile with the new rear gears. Wasn't expecting to have to make the shift to 5th but there was way too much track left not to; and I just tagged it when I shifted but it was enough to make the shift to 5th grind. I drove it around like that for a summer and it wasn't so bad; just a second or two pause between gears and it didn't grind. I was told to try the GM Synchromesh fluid. No grind. Gone. For years now. I put a new clutch in her and drained the fluid. Filled her up with GM Synchromesh again just in case. I hate running Chevy fluids BUT I can't argue with how well it's worked for me.I purchased a Z spec t5 for my fox from LMR, and it came with some royal purple trans fluid, I put that in and it grinds going into 5th gear if I’m above 2500-3k rpms. I looked online and people said that RP fluid is trash and Tremec themselves said to use non synthetic ATF. Did I ruin my new trans using that RP fluid? Or have any of you ran this fluid/owned the Z spec trans? I’ve maybe put 200 miles on it. Thanks!

How's your fuel mileage ? I have 4.10 gears and still get great gas mileage if I feather the throttle lol hard not to though...I went from 3.55's to 4.30's.
I didn't find the gears were too bad on the fuel economy, but restraint is required. Makes the car lots more fun around town, though she'll get through a tank of fuel if you're having fun.How's your fuel mileage ?
