Have seen over 300 posts from Windstar owners with the exact same problems.
Ford did a recall on the head gasket and reimbursed owners the full amount, and will cover the defect up to 60k miles.
Transmission is still an out of pockets expense for owners. Dealer would give full rebate per Ford motor company letter sent to me, had to contact local attorney general to get Ford dealer to comply with Ford directive.
Transmission problem was not corrected till later half of 1996 models (forward thrust piston made of aluminium vs steel).
