I suspected the shifter myself, which is why I disassemble, inspected and evaluated...Don't see how the shifter could be causing this...?It feels like the 1/2 (and 5/R) shift fork is not able to move far enough forward to completely engage the gears.It *acts* like the 3/4 fork is not able to move far enough forward to fully engage 4th...Which is why I made sure the shifter itself is not preventing the internal shift rail from completing it's travel. When pulled as deeply as possible into the 4th gate, the shifter is not out of swing travel.Open to discussion....
The distance between the base of the shifter and the end relates directly to how far the shift forks move forward and back, if this distance wasn't maintained with the short shifter, the forks wont move as far as they are supposed for the gears to engage.Researching the Ralco shifter I couldn't find anything for it regarding the an MKIII Supra, just the MKIV, if it was designed for the Wseries, that would explain why the forks don't move far enough.You might try shifting it into gear, then remove the shifter and see if you can move still move the selected fork more, if you can it would indicate the short shifter isn't designed correctly, if you can't, then that would indicate something with trans.
In my case, the shift shaft/fork is coming to a stop before the shifter runs out of travel... Which is why I don't see how my shifter could be causing this.
But, point taken. I have a W55 with a stock shifter in my other car. Tonight I will pull it off and stick it on the R154. I don't expect it to help, but it's easy enough to try that I definitely should. I will report back after I test this.
While you are at it, install the ralco and see how it feels in the W55.How does it act when you aggressively shifting through the gears, i.e., like you are at the track or pushing it on a twisty road, reviews seem to indicate it works better when driving aggressively than just cruising around town.
I will indeed try the Ralco on the W55...While I'm not impressed by the "feel" of the R154 (as compared to every other manual trans I've ever driven... T5, T56, T6060, T10, SR4, 3550, 3650, T45, TKO, etc etc etc), it seems to engage every gear just fine (including 4th) provided you shift it like you really mean it.If I shift into 4th with authority, it seems to engage ok. It's when I attempt to drive with finesse that 4th either doesn't engage - or partially engages then pops out. However, that makes me question if the shift hub EVER fully engages the dogs on the gear...The thought of ~400lbft being transferred by a halfway engaged gear makes me sick to my stomach!
I'm late to the game but after reading all the posts it sounds like you already have it figured out. If you have any questions let me know.
...As for internal details on differences between years. Its company policy to not give out any information on things like that so I cant help you there, sorry.
