is there a complete kit for a 4L60E transmission to work right in a non computer car?
l put a new 355ci crate engine with a carburetor in my 94' silverado with a 4L60E transmission but now the transmission is working properly, it only has drive & reverse no 1st or over drive is there a electrical kit that l can need to plug that transmission into & where can l purchase it?
It all depends on what else has been done to the engine, there are too many variables. For arguments sake, say that you bored your engine to 355 ci as part of a rebuild (why else would you bore it). If you did nothing else but replace all of the worn parts and kept the same heads and cam profile, the mere fact that there were not any worn parts in the motor could give you another 50 horse power, it all depends on how tired the motor was before being pulled down. If you are looking at a good condition motor and bore it out to 355ci your increase in power would be minimal. This would be the most inefficient method of gaining a bit of extra power.
formula for measuring the volume of the a cylinder is Pi r squared multiplied by the stroke and then for total CI multiply the # of cylinders: Bore=4.030 Stroke =3.48 Cylinders =8 3.14*3.48*(.5(4.030))*(.5(4.030))*8 10.9272*(2.015*2.015)*8 10.9272*4.060225*8 44.36689062*8 354.93512496 Cubic inches or more commonly known as 355CI
