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.

You can also go with Competition Clutch, if you got the S54 tranny, you can buy a 3sgte flywheel, 3sgte pressure plate, and 3sgte clutch disk with the right splines custom made for it, Competition Clutch will make it for you, and i used ARP bolts. the advantage is a bit bigger diameter. if you got the trans the little bitty stuff that tends to be forgotten besides fasteners if you dont have a donor car is the c-clips, that hold the shifter cables on the tranny side and shifter side, they are gold in color. Decide what you want to change for your mounts. gauranteed you need the manual tranny mount, i did get away with auto mounts at one point for the rest until i also did the front and rear but im still on auto mount on the pass side. but at least you can still use the auto axles. i'd recommend brand new master and slave cyl, dont use a used one. you want new ones done right the first time so you dont change it again. read up again on the ECU thing i posted those are some options, either get a manual ECU, get a manual gauge cluster, or just take out the O/D bulb on your auto cluster. also to get if its missing when you buy the tranny is the bracket that holds the slave cyl line if you want to really copy the oem style. at least get the slave cyl OEM since the price is not that bad, i preferred it over aftermarket oem replacements. and the wiring is covered in the swap sticky. GL with your swap.

If he's running an E153, can just run all 3SGTE stuff. flywheel, pp, disc. If he's running an S54, just order a factory clutch for a manual 6GC GT. The E153 WILL require different shift linkage though, an S54 can use normal GT linkage. Also, the E153 needs the different half shaft setup, whereas the S54 is, again, stock GTs.
