There is NEVER the need to replace an engine and a gearbox at the same time unless both are diagnosed to be at fault and are both diagnosed defective (the engine having no real effect on the running of the gearbox per se and the running of the box not affecting the engines normal operation), there may however be the need to remove the pair together to effect a repair to one or the other...this is not uncommon.
As for the route to take...repair or replacement.
A contaminated auto box will, through its nature, contaminate the rest of the box thus causing (in future) failure of additional components (clutches/brake bands), therefore repair often leads to complete replacement of said parts, subsequently a replacement to the non professional mechanic is preferable as guarantees and warranties will apply to the replacement gearbox. This will not be the case should a repair be made to defective parts that then lead on to contamination and breakdown of existing parts that aren't replaced, even though the repair and replacement of the original defective parts be sound.
