Tranny in need of help

[GenIII_4Ever]

Ok a few days ago my tranny started messing up by not shiftinh right and 1st and OD wanst working and when u take of it started u out in second and wouldnt shift past third gear. Now it works sometimes and other times i have no 1st or OD I scanned the codes and this is what I got.

2761- Torque Convertor Pressure Control Solnoid
0785- Shifting Timing Solnoid
0758- Solnoid B Electrical Problem
0753- Solnoid A Electrical Problem
0740- Torque Convertor Electrical Problem

Now I Think These Codes Are All Linked To a Bad TCC Solnoid But I just wanted to see if ne one knew something or what the hell is going on here.

id say replace the internal trans wiring harness first, and then if you still get some solenoid codes, replace all the solenoids, also when you drop the pan to change the harness make sure its not full of junk from a worn out trans, if it full of junk, metal and clutch material, probably time for a rebuild.

Ok Ill take a look at the pan contents and will try to get the new harness here soon i only get 1 day off so its gonna be hard and if any 1 has a price on these parts i would like to see how much this is gonna hurt my wallet thx

Have you recently installed a torque converter? Or have you done any other work recently? I wonder if you have a connection problem or possibly a power/fuse issue. The reason that I say this is because you have almost all of the trans related codes. Just an idea. Vince

There has to be a fuse for the trans. Look for something that says TCM. Are you having any other electrical problems with the truck? Maybe they share the same power supply. Just an idea. Vince

the only other problem ive had with the truck is the guage cluster went hay wire but i got a call back notice in the mail so gm is fixing that now but besides that all my electrical is a ok.Ben

Did the trans start to mess up around the same time as the cluster started having problems?
