I got a quote from MA Motorsports and I honestly can't believe what I'm looking at.
The quote is for the following:
1. New Z34 transmission
2. Install the following customer supplied parts: clutch, flywheel, csc elim kit, trans mount, clutch pedal and clutch master cylinder.

Total with tax: $3,412.78

Does this seem right? I was really expecting something in the range of $6,000 to $10,000

I got the quote via email and plan to call them tomorrow to talk more about it.

I'm thrilled with the price. Like I said, I was expecting a lot more. Since this is a lot lower then expected I'm going to speak to them about possible upgrades for the synchros. I dont want to go through this again in a few years.

I thought that it would smooth out as the transmission broke in but it has actually gotten worse. I'm now babying the tranny and double-clutching the 1-2 and 2-3 shifts to reduce further damage. My suspicion has always been that the synchros weren't working properly, but I'm no transmission expert. I have driven manual transmission cars ranging from mid-60s British sports cars, to a Porsche and numerous domestic cars over the last 45 years without a problem. I even had a couple of 5-speed Fords that had over 200,00 miles on them in which I had no problems with the transmissions, so I don't know.

I guess the first step will be to take it to the dealer to have them evaluate it. Knowing how these businesses operate, I'm anticipating having to fight with them to get them to acknowledge there is a real problem. Has anybody here had to go through the legal process to get Nissan or its dealers to do the right thing in cases like this?

Before you take any further action you should change your transmission fluid with a better quality fluid like Redline MT-85 transmission fluid and see if it smooths the transmission shifting out and makes conditions better.

Hey Unisyn
I'm in your area, Lake Mary, who (if you don't mind me asking) did your CSC work?
Mine is fine but I'd like to know my options.

Thanks!

Unfortunately the 6MT transmissions are well known for being notchy at times to shift. When you shift is your transmission is it making any noise that you know of? The 6MT transmissions in our Z’s are very strong and reliable I have seen them last 200K-300K miles really depends.

Changing your transmission fluid can make a difference.

Thanks for the good advice. I have used Redline motor oils and gearbox lubricants in the past in my Porsche and have always been very satisfied with their performance. I am planning to have the tranny oil and diff oil changed out with Redline stuff when I bring my car in for its 5K service and so I'll see if it improves things. Meanwhile, I'll continue to try to refine my 1 - 2 upshift technique to get smoother shifts consistently. Strangely, my downshifts into any gear, with SRM off, are all very smooth with no problem.
