Trans Problems My transmission started having trouble last night. When I push in the gas from a stop, the car accelerates just fine, but when I hit third gear, it's almost like it's in neutral--the rpm's go up freely, but little or no acceleration. It does this in third and fourth gear. It will occasionally lock up for a moment, then it does the same thing. It seems to have no problems in 1st or 2nd, though. I don't hear any kind of grinding noises - the only noise I hear is an occasional quiet rattling noise. Any idea what this could be? Torque Converter? Transmission? Thanks for any help.
$500 basically for just the parts, and upwards of $1500-$2000 for a highly reputable company to get it done. I was quoted $1400 from a good shop. It all depends on your area though. I just went and bought a used trans with 30K miles for $500 and called it a day.
Why don't you just save that $1500- $2000 and buy yourself a tranny thats not going to crap out on you again. TH350/400 4L80 ect. I did the entire swap froma t-56 to a th400 and it cost me $2050. Tranny, crossmember, torque converter, driveshaft, shifter, torque arm. You won't regret it.
