O.K., My car is running great now and I am having a blast driving it. I find myself wanting to manually shift it. Now I am kind of like Fred after he took his car to the races, am I hurting it?

I also am getting interested in the upgrade chips for motor and transmission. The transmission obviously shifts slower than one that is a manuall shift. Does the upgraded chip effect the crispness of the shift, allow you to stay in a particular gear longer. or what? Just what do they do to the driveability of the car. I am pretty happy with it the way it is.

Is the chip upgrade from Stillen the most desirable one?

Thanks in advance!

There are 2 chips made.One for engine (ECU) one for transmission (TCU).

They are both made by JWT and at some time were offered by the NICO store at good prices as well.A couple of members have them from Stillen and a couple from the NICO store (which hopefully will be resurrected sometime).

Another member "aacomp" who you might wanna email, owns a programming shop and offers (or at least used to, you might wanna email him via our members archive), a chip also.He sells his for very inexpensive basically cost and I almost got one but then I bought this car that has teh chip in it already anyway (both of them actually).

Manually shifting the car wont hurt it unless you force a down shift at hispeed/rpm, in all other cases it acts similair to a normal shift.One of the best manual shift applications is in town when going off the line and holding first that way, this give great effect.

Anotehr enjoyable way to accelerate is to do kickdown from 25 mph or thereabouts it will shift all the way into 1st.

Oh I just saw you have a 94.

You have first gear start anyway, so much less (if any) need for the transmission chip.

Less need for manual shifting as well.

A heavy right foot is better than shifting manually. If you floor it you'll shift close to redline.

Just remember that it's hard to drop into 1st gear unless you're going under 20-25 mph.

I am looking at having the transmission on my 1994 Q45 rebuilt by level 10, as I am testing the limits of the stock transmission and torque converter.

A full blown rebuild will cost me about $5,000 by the time I pay shipping costs, duties ect from Australia.

Before I go down this track, I was hoping to get feedback from NICO members on Level 10, particuarlly from members who have had a rebuild done by them.

Comments anyone?

I think Todd Land has one of their rebuilds in his old car.

You could buy the transmission in his new car (or any other correct junked model in the USA), have it shipped to Level 10, then shipped to you. Probably a lot cheaper than shipping a core from down under.

Although I don't shift between D/2/1, I do use the overdrive button quite often, in city drive, i usually keep it off and then when I see a long road, turn if on.

what scares me is this is a tiny plastic button, I hope my repeated use doesn't fail its springs or whatever is within it, and then I land up paying $$$ for getting it fixed.Any experienes on this one?thanks97 Q45, 85K miles.
