Always wondered which is the better tranny. Dont care about T-56 or TKOs, just in the basic stock ones. Which is the best, which can handle the most power, which is cheepest? My T-45 shifts way nicer than my T-5s and I can shift it quicker, may just be the MGW but I think there is more to it. Please enlighten me

3650 by a long shot. When properly driven, a 3650 can take quite a bit. Even being behind a KB'd 4v Cobra motor with 550whp. I like my 3650.

I've been beating a tr3650 at the track almost 2 years. I bought it used 4 years ago for 350 and it has worked great ever since. It has never seen less the 380 rwhp.

it seems like the 3650 had good batches and bad ones. Some people put thiers through hell and they come back for more while others have problems at stock power levels. I put one in my 96 about 5 years ago and am very pleased with it.

It seems like both the T45 and the 3650 have good and bad batches. On my 2000 I had a T45 (one of the goods ones) and I LOVED it! On my 2002, I got a "bad" 3650 and I hate it.

I have tried tons of different fluid and different quantities and nothing seems to stop the rock crushing sound... Soon, I will look at getting a T56!

Had a T5 in my 95GT with over 400RWHP. It had H/C/I and a PRocharger P600B with 11.5lbs of boost. IT only had 3.08 gears though, so that could be a reason it lived through a lot of track time and freeway blasts. My other two T5's were in stock 5.0L fox bodies. No problems with them either. I replaced my T45 in the Cobbra, but someone had put 30K on it before me, so that is why it failed....previous owner could have had something to do with that.

T-5 in our project fox is sweet. It just stems down to how the person shifted before you had the car IMO. We got the car with 100K+ on stock everything. It shifts smooth.

I havent' had a problem in any of the transmissions, but my 3650 shifts the smoothest. I had a T5 in a v8 Ranger, and I beat the crap out of it. Did numerous launches on slicks. The T-45 in my 01 GT took a hell of a beating, and never had a problem, except for reverse being difficult to engage. I did launches on 315 drag radials on that trans regularly. My current 3650 has been nothing short of amazing, although I haven't done any track launches on it yet. It's at the highest mileage of all of my transmissions, and it shifts the best. I did put in synthetic fluid recently, so I haven't had any of the cold grind issues that these have. I am getting an MGW in a week, and that will make things even better. Out of all of them, I would definitely put a 3650 in on preference. It's the newest design, reverse engages smoothly, and it handles a good amount of power.

I wonder how many people with bad 3650's also have aftermarket shifters. I still you a stock one with a short handle. The t-45 I had before developed a bad mainshaft bearing and made noise during deceleration

The 3650 is the strongest on paper.

The t-5 however is the simpliest to rebuild and also the best shifting IMHO.


My 3650 shifts fine with an MGW shifter. I have 52K miles on it and no issues at all. Shifts great too.

I have 1 gallon of Castrol Syn-tork in my 3650. Look it up, about $80 a gallon. It is used in severe duty trannys. I also have a steeda tri-ax with the UPR rock crusher shifter handle. Shifting this thing is a dream. Just slides into gear. The shifter handle made a big improvement over the stock tri-ax handle.

I couldn't agree more. The best T5 I ever had was my 92 GT...97K Stock...perfect!! Car must have been treated like a gem for the first 95K it was driven.
