Looking for a break down of a 99 saturn sc1 A/T transmission, diagram, anthing to tell me what i am looking at while working on it, just want to know whats what with just the transmission


Few vehicle manufacturers produce their own auto trannies but tend to buy them in from specialists, ZF, AP, Borg Warner, etc.

Vehicle manufacturers tend not to publish much information about the auto trannies they use but find out the origins of yours and apply to the manufacturer and you should discover lots of information.

1774 and 1775


There is probably no need to contact the BAR though you always have the right reserved. Trouble Code P1774 indicates your Mini's rear wheel speed sensor lost its signal, and trouble code P1775 indicates the right rear wheel speed sensor lost its signal as well. Both more than likely triggered during the dynamometer portion of the smog check inspection; while the front wheels are turning and the rear wheels are stationary. During this time, as far as the ABS system knows, the rear wheel sensors have lost their signals.
After a computer reset and driving your Mini Cooper for a few miles everything should return to normal, as apparently they have; and you've passed the smog check. Should the check engine light return in the near future for the same trouble codes P1774 and P1775 we'd recommend inspecting the rear wheel speed sensors for possible debris build-up. Since these trouble codes where triggered during the smog check and smog check machine failure we can assume the trouble codes were temporary and not related to any physical problem with your Mini Cooper.

Torque converter clutch system,stuck manufactured controlled transmission


It is probably the control switch inside the transmission pan this happened in a lot of GM mid size cars. back in the 80's and early 90'sJohnny

I have a check engine light on my 2005 forenzaa. Codes reading p700 and p1884.


po700 is transmission control problem and p 1884 is manufacturer control transmission. both codes are the same, get p0700 fixed and it should fix them both. fot p0700 you need to have the transmission computer checked for the problem code to tell what is wrong.

What does these codes mean P1781, P0731, P1784 AND P0700 AND HOW DO I FIX THEM.


p1781 is manufacturer control transmission, p0731 is gear 1 ratio incorrect, p1784 is manufacturer control transmission, p0700 is trans, control system malfunction. all of these codes refer to tranny.This code normally points to a faulty transmission control module, but this is an expensive part and you should have an experienced Dodge technician diagnose the problem first. or a transmission specialist. the other codes are probably associated with the p0700 code. have a good day !

I have a 2001 lincoln contintental the code that pops up is 1744, can somone tell me what that is and how to fix it?


P1774 - Link Gear Shift Module / TCM

This means the computer has detected a slippiage. First thing you can do is a transmission pressure test, it should be 62-81 psi while in park or drive and 110-120psi while in revese. If pressure is low the problem could be the pump, a external or internal leak, pressure regulator valve, or epc soenoid/circuit. Otherwise you could start by replacing the EPC solenoid and the pressure regulator valve. If that does not fix the problem you would probably want to bring the vehicle into a transmission shop to have them diagnose the problem.

The EPC solednoid is the most common cause of this from what I'm aware but the torque converter itself could be the problem also but you would want to have every other possible cause checked before replacing the converter since that is expensive and time consuming.

Hope this helps (remember to rate this).
