Auto to Manual Conversion
By Scott MDT
Foreword
The article I am writing is from my personal experience in converting
my 1990 Celica GT w/ a non-ECT transmission. If you want to convert
your car and it has an ECT controlled transmission you can use this
as a guide, but there are some things that are different such as
the ECT controller is built into the ECU. So there will be some
wiring issues that you will have to work out on your own.
I have heard a lot of people talk about wanting to convert their
car, but I have never seen one converted or seen any type of detailed
instructions on the process. I wanted to convert my car and have
it done in such detail that you couldn't tell that it wasn't built
from the factory that way. But I also wanted to help others by giving
a well detailed how to so when you are in the middle of the conversion
you aren't gong to get surprised with something out of left field.
You can convert you car in a 3 or 4day weekend if you have everything
on hand and a fairly decent set of tools. One of the big things
is that you can't tear out your transmission and be half way back
together and realize that the bell housing bolts are different lengths
(and they are). You can't just jump in your car and run down to
the parts store and get the extra stuff you need at a moments notice.
I was very lucky though because I work for a Toyota dealership and
had access to a lift, air tools, and a large bolt selection. I was
able to come up with the sudden extras I needed.
There is so much information to give you that if I threw it out
it would over whelm most people and you would have trouble knowing
where to start. So I am going to break it down into chapters to
help make things easier. First chapter: Parts list and compatibility
issues. Second: Master cylinder, clutch pedal, and hydraulic system.
Third: Shifter and cables. Fourth: Transmission. Fifth: Electrical
wiring and schematics.
So let’s get on with the conversion……..
