Hard shifting A833's usually have one of two things in common, or both. Clutch plate departure and shifter issues.

As mentioned, ask McLeod for the departure gap and set it that way. Do not use pedal free play. For those of us running OEM replacement clutches that would be .060". Rebuild your clutch linkage system. New bushings, dump the rubber bushing int he clutch fork for a metal one, new ball studs, replace anything worn.

A good shifter is a must. I like Hurst Comp/Comp Plus. You HAVE TO adjust is properly. Using the plastic pin included is not best. Get a drill bit that just fits thru the alignment holes, the tighter the better here. Then adjust your rods so that they are centered up in the shifter levers. Use metal bushing not plastic in the shifter levers, both at the trans and the shifter. Use spring washers and/or shims to remove any slop between the rods and the levers, but not so much that they bind.

One this is all done your A833 will power shift properly, assuming the trans was rebuilt proper as you mentioned.

They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
