The T-45 transmission has a non-synchronized rear drive. This allows for less parasitic loss of power through the transmission in the forward gears.

Reverse will do that, it's normal. The best way is to try an not "force" the transmission in gear. Either let the clutch out and then disengage the clutch again and try or try putting the car in 1st and coming off the clutch just enough to make the car "move" as minimum amount as you can. Then try going into reverse.

The T-3650 transmission I believe ('99 and up I think) does have a synchronized reverse and shouldn't grind or be hard to get into reverse.

Just a note on fluid changing. I was having problems (grinding) going from 1st - 2nd esp. when cold on my T-45. I figured the syncro was worn. My friend suggested changing the fluid. Cheap fix that worked. I can't believe how much better the trans works. He says Ford doesn't have a service interval on manual fluid change. My car has 45k. He just put in the Ford ATF. I'm going to let it clean out everything and change to a synthetic in the fall before the weather gets too cold.

Tom can probably add expertise to this but I believe you're trying to mesh three gears when going into reverse. By going into first before going into reverse you use the syncronizer to stop one of the gears allowing an easier engagement.

Yeah...seems to be a common problem. For whatever reason, popping it in 5th before reverse seems to help too. Changing to full synthetic this week so I'll see what the difference is.

Got the synthetic put in yesterday and there is a slight difference but the big one for me is that my shifter and tranny area stay cooler now. For what ever reason that area would get pretty warm, this is only magnified by the billet shifter I got on there. Happy so far...

One of my cats just broke apart on me though.. Gonna try to get that fixed this afternoon

I have had similar issues when putting the transmission in reverse (87 Fort Escort) which of course is not a tremec but a borg-warner transmission. Since there was a lock out lever when going from 5th to 4th gear downshifts, I found it easy to get into reverse by first moving the shifter to 4th rear then to reverse with the clutch engaged of course. Since having put 264k miles on that car, it has become routine and I find myself doing it with my Mustang. I never had any problems getting into reverse. I also never park the car in reverse either. I usually use 1st gear when the car is parked. I also had a few instances of grinding gears when getting into first while sitting at a traffic light, for which I found it less grinding if I move to second gear then shift into first as it seems to slow down the pilot shaft (I do not sit in traffic with the clutch pushed in since this will cause the splines on the pressure plate which pushes in the throw-out bearing). With the engine running and in neutral, the pilot shaft is still rotating and will have momentum. By shifting into a gear while in neutral will slow down the pilot shaft while the clutch is engaged helps when selecting either first or reverse. Give it a try. You may be surpised that it works.
