LT77 shifting vs R380

I know, this has been discussed in previous threads, and I have read through them for a few hours but not found the answer to my question.
I have a 94 with the LT77. This may sound silly, but what is the correct manner to shift? If I am in 1st, and firmly bring it right to 2nd, I get a slight vibration, not grinding, no noise, but kind of a gear finding feeling. If I shift from 1st, slight pause in Neutral (.5 sec to 1 sec) and then go into 2nd, it is perfect, no feeling of vibration or anything. Is the 2nd way of shifting the "correct" way for this tranny? Thus the reason why some in the US market did not like and had the dealer switch to the R380?
I have to say it takes some getting used to, as I am just used to going right from 1st to 2nd no pause just slam and go. Is this the euro type shifting I am trying to get used to?

The 2nd way is it. You need to feel it out and let the gears align as opposed to slamming it. Its not a 911. Treat it like a woman.

EVERY gear box needs to let the synchros mesh. You need to have a sensitive hand and feel it.... Slight pressure against the synchros and it will fall into gear when everything is aligned. Forcing the shift wears the synchros out.

There should not normally be much of a pause required when upshifting. It could be partially worn synchros or use of the wrong oil. Do you know what oil is in it?

Thanks for advice guys, I think it's just going to take some patience and getting used to it. Hell I haven't even put 100 miles on her yet. Had tranny oil checked by my service guy, it looked great. The pause is seriously like 1 sec and it slides in no issue. I plan to drain out oil this spring and put in new.
Quick question, I need a new shifter knob, are these available for the lt77? Didn't find them on Rovers North.

Yes, but what is it? To thick or too slippery of an oil will cause them to shift slow.

No idea what brand or type, previous owner had that done. I want to put in Redline Auto trans fluid when I change it out.

You should use Redline. MTL or similar manual transmission fluid. The original spec was ATF but this works better.

Shift slowly and you will be rewarded.

Don't force it into any gear, including first when you're stopped.

On a prior post you inquired about what tranny fluid to use. The consensus was Redline MTL. Guess you found the mechanic that knows better than this group.
