I think I lost my tranny tonight???
OK, 6 months ago (my last drag race) I caught hell getting the car in 3rd gear. The car sat for 6 months before I started it up and ran an autox last week. I didn't have any problems driving to the event (1st-5th) or at the event (only 1st and 2nd gear). I wanted to do another drag this week so I change out my motor mounts (I thought that was the problem) a few days ago. I went to the track tonight and still couldn't find 3rd. It was like it just wasn't there under heavy loads. I drove the car home (1st-5th) and rushed off to work tonight so I haven't got to play with it yet. I know 1st is way over to the side (kind of like a reverse gear - just on the drivers vs pax side). What the hell did I do? The tranny has 220K miles on it (I think) and the car has a late model LSD on it. I'm torn between:
1) pull it out, inspect and fix the problem (no idea what I am doing <G>)
2) buying a used 5 speed
3) swapping to RX7 stuff in case I ever go up on the HP
Suggestions, ideas, comments, help??? Again, it seems to drive fine at normal speeds with the exception of 1st feeling like it is way over to the left hand side.

i just took a tranny from my 1995 parts car with 90k miles on it. changed the oil to syn and took it out for a spin. gears changed awsome, then i started to take it higher up in the rpms at full boost and going from 2nd to 3rd shifting at redline , it WOULD NOT go into 3rd. id have to force it like a bitch and listen to the grind or let the clutch out between the shift and then stick it in and slide it in. ******* pissed, but yea the syncronizers dont do much work while your just driving around cause they only need to change the other gear by 250-500 rpms and while your shifting at redline they will need to change the next gear 1.5-2.5k rpms.

I have heard other stories of people not finding 3 during a 2-3 shift under real heavy load. Seems common with people putting 250+ hp through the 5 speed. I've also heard that going to the mazda competition mounts will help get rid of the problem as it's caused by excessive flex.
Don't know what's up with the location of 1st, but at least it still works.

Part of it is driver error. I've found that if I'm actually paying attention and not just pushing the shifter around that it always goes into 3'rd. But it's definitely harder than when I'm just driving casually.

same issue. i replaced the mounts about a year ago. not much difference. the car is fine in daily driving situations, but if i'm driving hard, like in the mountains, shifting a lot, running the car out it's range, i sometimes can't get the car into 3rd. the car isn't boosted right now.
once it cools, it's fine.

It will be interesting to see what is inside the tranny (I have no experience with this).

Yeah but our 5 speeds use a 4.1 or 4.3 rear diff. 5th gear on a 5 speed is .814:1. 6th gear on a 6 speed is .843:1
A 6 speed with a 3.9 (standard w 6 speed) or 3.6 (available in some countries w 6 speed) would be pretty sick.
.814 x 4.3 = 3.50
.814 x 4.1 = 3.33
.843 x 3.9 = 3.29
.843 x 3.636 = 3.07
