5sp trans swap from 5th gen, Is it feasible? Options

[Xander_X]

So, since day one of me purchasing my '99 GT (about 2 months ago), I've wanted to do a transmission swap. I bought this car cause of the low mileage, great condition and decent price. But I hate this auto trans, I swear the trans ECU is retarded, I can't quite find any reliable trigger point for downshifting. Sometimes I floor it and it bogs, sometimes I floor it and opens right up (normal for these cars?). I hate not having the power when I want it. So after all my research, I've just decided to buy a complete donor car as there are too many little parts and I figure I can just part out the rest of the car and probably make back a good chunk of the money.

I haven't started looking for a donor yet but I wanted to know if all or most of the parts from a 5th gen with a 5S would work? I just didn't want to rule it out in case I got the chance to pick one up cheap. Anyone know? If it's only a couple parts that are different, then cool ... if more than a couple, I'll just make sure to get a 6gen.

Here's my opinion from having used both transmissions.

I like the 6GC manual better. The S54 is a much better transmission. The double-cone synchros are really noticeable using just regular trans fluid (which is what my actual 6gc has).

I had a 5GC before this, it was a 93 GT. The S53 is OK at best. The fact that the S54 is much better made is worth the price difference to me. Unless you want the trans for the sake of being manual, I would suggest getting the S54 (6GC trans) because the S53 is only halfway decent spending some good $ on Pennzoil Synchromesh or Redline MT-90. The S54 with either has smooth-as-butter shifting.
