Anyone know when 4L60-E transissions came out? I think it was in 1992. An 88 transmission should not be an electronic version. Should only have a lock up converter. Thats not worth installing the computer for. The lockup enable is pretty simple. You need a 12V ignition source through a brake switch. The brake switch will unlock the converter when you come to a stop (lest ye engine stall). The internals are wired a variety of ways, but essentially you want the TCC solenoid wired in series with the 4th clutch switch. One step better is to purchase an adjustable vacuum switch and put it in series with the circuit. It should be adjusted to drop the converter out when the manifold vacuum drops below some value (depending on the motor, cam etc.) I think Jet performance sells them. As for painless, I can't say yes or no. You just need an OEM style conector to go into the transmission. Beyond that, it's your choice. See what Jet Performance has to offer.
