Question about Cars & Trucks

1 Answer

I have a 1994 GMC 1500 ext cab, 2wd, with a 5.7 V8. when I bought it I noticed that the tranny fluid was brown in color and it would shift hard into 2nd gear, more so when cold. Now the truck has seemed to lost all gears. If I put it in reverse it seems to creep forward, in drive I get nothing at all now. Also, when starting up the starter is much louder than normal and when I give the motor some gas and release the pedal I hear a whining or slight grinding. Can anybody give me some input on what the cause of these problems are?

Hi Charles, Pull out the dip stick from the transmission and smell the oil. If it smells burned with the other symptoms described it sounds as if the transmission brakes and clutches have already been damaged, which basically means a replacement transmission or rebuilding the one you have. Sorry to be the harbinger of bad news, but if I'm guessing correctly, you expected it? Regards John

Take a look at the down shift cable and make sure its not broken especially were it connects to the throttle linkage.And maybe try cleaning the electrical plug that plugs into the trans.Its about a 7 to 9 wire plug.They tend to collect water and short the wiring out.

I have a 92 GMC , 350 engine. I have no reverse and no overdrive. Any suggestions ?

I'm suspecting a 350 turbo hydramatic tranny. Pull the tranny stick inspect the fluid color and level. If fluid is brown/black and smells burned, the tranny needs an overhaul. If fluid level ok and color reddish, I would suspect a clutch issue and the tranny will require further diagnostics/repair

94 F-150 4x4 e4od Strange shifting.

That's what I said about my Mustang Gt when the tranny went out on it, it sat for 5 years until I finally sold it. I started looking for a replacement tranny for it before I decided to sell it and found a few on ebay for a reasonable price Shipped and Guaranteed for around $1500, beats breaking open the old one then sorting through whats good and bad, kits cost $500 alone. Then doing the rebuild and hoping it's all good with no guarantees on if it will or how long it may last. Not to mention the mess and time and frustration of taking on the task. Just removing it will change your mind on doing a rebuild. That always seems to be enough work by it's self, having the other tranny right there to put in will make it a 1 day task. No parts to loose or find out that they don't fit or the case needs to be machined, many things come to mind.

It takes high rpm to shift my 91 chevy c1500 4x4 out of first to second, it sounds like truck is going to blow. Whats wrong?

there is usually 2 component to this, all related to the transmission. First , loosen the kick down cable,If you cant figure how to loosen it, just disconnect it from the throttle body. then test drive to see a difference. IF still shifts very hard, you may have a "shift kit" installed. this was done when the tranny was rebuilt.. I personally install extremly hard shift kits in my vehicles, my 1992 gmc K 1500 X-cab will shift so hard it "BARKS" the tire, and slides the back end of the truck over 1 foot, it feels like the truck is going to break. I LOVE IT...

Transmission dosnt shift when truck warms up

I have a 1995 GMC 1500 with 5.7 truck that the ABS Light comes on and then the tranny starts jumping gears and speedo goes crazy- Changed ignition switch and that did not help.
You said that you had changed the speed sensor on the tranny and that did not help ?? If so that was my next step. Let me know if you find and answer and I will do likewise.

1996 GMC Surburban 1500 2wheel drive. Transmission shifts hard, turn engine off, crank engine and drive off ok. After a while it starts shifting hard again.

what RPM's is it shifting at?If it seems to be shifting a lot more then usual it could be a torque converter problem(locking and unlocking),for now I would try having the tranny serviced and see if the shop can adjust the shift points,also check the tranny fluid for color,amount,and smell.It should be a pinkish to red color and not smell burnt,as far as checking the fliud level run it around until the vehicle is up to running temp and follow the instructions on the dip stick for proper procedure.good luck.
