I own an automatic Forenza for a few years new.And for what we have paid for the car and how it served my wife and albeit some minor problems,I can say that I'm satisfied for the overall value of the car.

So, I have been lurching for a "5 speed" Reno/Forenza for my daily driver to replace my "Sunfire" I have now.However, the 2002 Sunfire doesn't have a timing belt or a quirky TRS and gets better MPG than my wife's Forenza but I'm so tempted to get a manual transmission Forenza or Reno.

I have seen a good bit of "5 speed" Forenzas on Craiglist over the past 6 months with problems with grinding gears ,bad manual transmission,clutch and throw out bearing that it gets me to think twice about how reliable this gearbox is.

Who the manual transmission is made by? and what's everybody's insight about that?

Thanks

I bought a used 07 Forenza 5sp about 2 months ago. My MPG with 40% city / 60% highway has been 32 mpg driving conservatively (70 or under on the highway). When it was cold out (under 40F) the 5sp was difficult to shift until it warmed up - my Nissan Altima had this same annoying characteristic. I never gave a thought to possible problems with the manual as I never had a problem with the manual transmission in 4 other cars.

I have a good amount of experience with the manual transmissions in these cars....

I've destroyed two 5speed gearboxes due to the additional power/torque I've put through them before doing a 6speed conversion. The commonly accepted torque rating is about 200 lb ft for these gearboxes.

Overall the 5speed was an OK transmission while it lasted, shifting was decent enough but not super refined. The throws are fairly long with the stock shifter, but this is mostly due to the design of the shift linkage/system. The gearbox model/code that comes with these cars is the D20, which is a derivative of the earlier Getrag F20 transmission. The primary difference being the D20 uses a hydraulic clutch release system instead of the cable operated system on the F20. Also consensus on various forums over the years seems to indicate the "D" designation also means it was manufactured for/by Daewoo using the same design but also ended up being a weaker version of the gearbox overall. This wouldn't really matter for you if you aren't planning on doing serious modifications such as a turbo system.

You can read about the F20 here: F20 manual transmission - Wikipedia, the free encyclopedia

I don't find any specific good information about the D20 to link you, but if you just drive normally, use quality MTF and don't abuse the transmission it should last a long time.
