Engine Performance problem
1985 GMC C1500 V8 Four Wheel Drive Automatic 10000 miles
Hello I was wondering if you could help me i've talked to several people and they have no clue what i'm talking about.
I just got my truck 4 months ago with 10,000 miles on the motor (rebuilt) and now I'm not sure whats making the noise the motor, transmission or transfercase, or maybe the rearend. What it's doing is making a knocking noise when you are in drive and holding the brake and giving it gas to the point that it wants to spin it's making a loud banging noise constantly but as soon as I slam it into nuetral out of gear it stops. But when I removed the transmission with the torque converter it stop cause I can't hear it anymore and when I first got it I assumed that the transmission was rebuilt and I was under the influence it was the torque converter.I'm not sure I though it was the transfer case too but not sure if it could slip and make a loud noise, cause it all started one day when I was coming home from work and all of a sudden it went out of gear, and I coasted a while, and it made a loud wining noise at that point and I thought it was the transmission and I put it in neutral and it made a grinding noise I know why that happend but why would it go into neutral
my truck has a 6 in lift
307 sbc with 350 internals
35 in tires
and th350 turbo
Oh, and when I slam on the breaks it goes into neutral in order for me to get back into gear I need to put it in 4 low and then back into 2 high for it to work
have the same problem?
