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.

Sounds like a lot of "if's", "might's" and "maybe's" .... I'm probably better off playing it safe, spending a little more and driving out of my way to get a 6 gen. Tweak said that because I have OBDII, I would either need to get my ECU hacked or a manual ECU. I don't know why I can't put a resister in it like an OBDI, but I trust that he knows what he's talking about.

theres no ifs mights and maybe's if you do the physical inspection between the two trannies, pedal, etc. its doable but you need to physically confirm it yourself. i can believe they are similar if not the same (maybe the mounts are different and shifter assembly). the reason why you think its might or maybe is because if i had both cars in front of me I'd know already but i dont. Your concern is to get as much as possible needed from the 5th gen. the rest you source from 6gc used, oem, or aftermarket replacement.

Use the auto to manual checklist to compare.

im sure for example you need to buy a shifter bezel, shifter assembly, maybe cables (but if you are buying the donor car, you can try it), and so on...because there are some things that 6gc is just different period, you wont be able to get everything from a 5th gen, so you need to get as much as you can that is compatible and you need to compare it by looking at it or checking someone who has a 5th gen.
