1. Slow, slipping or no reverse: low/reverse clutches are worn out, fluid leak in the reverse apply circuit, or broken sun shell. It is possible to remedy a fluid problem by removing the check ball from its cage in the case in the rear of the trans may help (must remove valve body), or adding a high-viscosity additive such as Lucas Transmission additive or other seal restorer product.

So is there anyway to diagnose this without diggin into the trans?

Info: 98 k1500. Took on quick test run for first time in few months after doin intake and mpfi upgrade. Checked n topped off all fluids. Shifted thru gears ok. Turned around in a driveway and backed out no problem. Bout hour later i go to run to town in it and reverse is almost a second park. Truck pulls forward fine, let it coast backward in nuetral then put in reverse it stops.

Not sure about the reverse issue, but I'd definitely throw a factory MAF back on regardless. Those aftermarket MAFs really screw with the tuning. I doubt it will help the reverse problem but it's worth a shot.

Dropped pan, new fluid n filter, cleaned out pan and reinatalled. Also put in a factory maf. I got truck on stands and when i put it in nuetral the drive tire takes off pretty fast like in low1. Am i maybe havin an electrical or linkage issue?

Rear wheels are tough as hell to spin my hand. Wonder if the diff is crappin out n thats my issue? Motor seems to struggle when i put it in reverse
