I just got my 1993 Chevy 3500... Auto trans, 4wd, 6.5L-TD. It has 130K on it and 1,200 hours on the engine, it was a fleet vehicle and had a pintle hook on the back though I don't know if it was used or what it was used for.
I just bought it from a friend and it runs great. I was told that it has trouble going into overdrive but did sometimes go into overdrive. I picked it up last night and it never went into OD. I drove it for about an hour, mostly highway at 55mph with the engine revving pretty high. It shifts a little hard into second (around 15mph) and shift smooth as silk into third (around 25mph). There are signs of a small ATF fluid leak, I'm not sure from where. The trans fluid is up to level, smells fair and is still red. The temp gauge in the insturment cluster does not work, all other gauges do however. The glow plugs are all new and though it start right up, even in the cold, it runs rough for ~30 seconds and the glow plug light will sometimes flicker on and off during this time. Also the interior light does not work due to either a fuse or wiring. The truck was stolen and though there appears to be no related damage, a couple wires around the steering column were cut to take the CB radios. The cut wires appear to only be ones from the radios and not any of the truck's OEM wiring.
I did plenty of searching and it sounds most likely that I simply have to troubleshoot the problem with the coolant temp gauge/sensor. I also read about a temp sensor in the trans pan but didn't see any way to test it. I plan to pull the trans pan to change the filter and fluid, can someone tell me how to test this sensor?
I'd also appreciate it if someone could tell me how to tell which trans I have.
Lastly, how do I tell if the torque converter is locking up? This is my first automatic truck so I don't quite know what I'm suppose to feel it do.
Thank you!
