Default W58 shifting problems

Hello everyone, some of you may know I but recently I ran over a cinder block in the middle of the road that cracked my transmission mount. I drove home fine, no problems. The next week I started to have shifting problems. I have a hard time shifting into gears above 3k RPMs. It seems as if it doesn't want to go into the gear unless I let the RPMs drop. I went ahead and replaced that tranny mount and it still has the same problem.

Now I'm thinking this could either be that the clutch got uneven wear while I driving with the transmission without the support mount(causes the tranny to sit lower) and now needs replacement. Or hopefully the transmission doesn't have any internal damage from that cinder block I hit.

What do you guys think? I'm probably going to have the clutch changed out in the next month or so.

clutch shouldnt matter, even without the mount, its bolted to the engine, should be even wear still...

I doubt internal damage from the block... it would need a lot of force to hurt the internals, unless the casing cracked?

The tranny casing looks good, no cracks or anything. Can it be a bent output shaft? I'm clueless on what it is. Fluids are all full.

It takes more than just the weight of the transmission to bend that input shaft. If it was bent, it would vibrate like hell.

Does it make any new vibrations/noises?

If it broke his trans mount, could it have bent something internal to the shifting mechanism?

This is the later W58 that has the remote shifter and it has alot of linkage that activates when you choose a gear...maybe something is bent?

Maybe the throwout bearing is partialy unclipped from the spring in the tranny?

This is what the unusuals are

Before accident = no problems all smooth

After accident
-Rough road driving above 50mph+ obviously because of the broken mount
-Shifting was okay for about 3-5 days.
-Then I started to notice that the gears got rough to engage.
-I think during that 3-5 days of driving with the transmission hanging down partially it either bent or warp something with the transmission.

Fixed the mount and the rough vibrations on free way went away but still hard to shift to gears.

I'm going to try to replace the clutch and see if it helps. The clutch does slip from time to time. Im not sure if this would cause it to not be able to shift above 3k+ RPMs. Thanks everyone for the input. Last thing I want to do is get another tranny. If my w58 is shot I'm going to get a r154.
