    Default 4l60e shifting problem?

    Hi everyone,

    My transmission has been acting differently, but I don't know if this is normal or if something is getting ready to break. Lately when I accelerate slowly, the RPM will go up to 2700 before it shifts into 2nd gear. The thing is, though, it usually shifts below 2,000 RPM when I'm driving slowly. If I take my foot off the gas when it's at higher RPM, it upshifts normally. The RPM are about 200 higher on the highway when I come to a hill than the usual 1800 that I'm at when I'm driving 70 MPH.

    It seems to do it more when the transmission is cold. I checked the fluid level and it's full.

    Here's my stats: 95 LT1 and transmission with about 75,000 miles. Fluid and filter changed 4,000 miles ago on a transmission I bought used. This is in an '84 Jaguar XJ6. I reaplaced the torque converter (1700 RPM I was told) 4,000 miles ago.

    Any ideas? Is my torque converter just breaking in or is something else going on? I'm new to these transmissions.

    Probably a result from not having the wiring checked like i told you. The TCC feed has to be wired through the brake switch with a relay to work properly. I remember you replacing the 2-3 solenoid and having a code tuned out or something. The TCC is also related to the circuit. But it does sound like your trans is slipping which could be any number of things at this point.

    A new TPS fixed the problem, so I guess I lucked out.
