Why will my 1987 Ford Thunderbird not go into gear?

Answer 1

If your T-bird is an automatic, try checking the transmission fluid level.( running, in park, engine warm) If low fill to full line. If the gear selector will not move, then it is possible you have a problem with the shift-interlock or the cable and/or linkages. If your T-bird is a manual, first check fluid in the clutch master cylinder. ( on the firewall near the brake master cylinder) If low ,add to the full line with brake fluid. (DOT 3 I believe) It's possible you could have a bad clutch master cylinder, or a bad clutch slave cylinder, or a worn clutch. Maybe even an internal problem in the transmission itself. Hard to tell without more information, such as; manual or automatic transmission, is shift lever moving but car won't move (a/t), is the transmission grinding when trying to put in gear ( manual ). These are just a sample of things one needs to know to "TRY" to diagnose your problem. Hope this helps.....
