Tremec 3650 synchro replacement

Fixing my grinding 1st gear.

After doing a lot of research these transmissions seem to not like synthetic fluid. I’ve done 2 fluid changes on my 2005 mustang gt with Mercon 1 dex III and haven’t had a single problem with the transmission. People need to stop putting all kinds of crazy synthetic fluids for it. I won’t even use Mercon V.

My synchros are really bad on my 04 mustang. This is gonna be a really helpful thanks man! :)

Edit: tl:dr I decided after watching some other vids that I am just gonna buy more trans fluid and drain it again just incase theres any metal in there or incase the fluid broke down or anything. But I won't rebuild it yet

My slave cylinder is dying again on my 08 GT, and it already caused my clutch to not disengage or engage properly which in turn has cause clutch chatter and a rough ride. I have been driving my car for a few weeks like this (I don't drive it every day thankfully but for occasional short trips) and I know my transmission synchros are doing double the work now because its harder to shift and sometimes reverse gear slams in. I hope I haven't shortened the life of my transmission components by too much already, I am hoping to do the clutch job by this week. My drive shaft is on the way out so I have a ford aluminum one standing by and I have the components to set the pinion angle and all of that, and I also have some bmr poly engine mounts ready too. I really can't wait to throw this all in and have my car back up to speed again. I just spent like $550 replacing the ford phasers and solenoids too because one was going out even though it was oem and my engine timing was off. Things are piling up lol. But anyways I am debating on whether its worth looking into rebuilding my tranny or not as a preventative maintenance measure. When the slave cylinder works though, shifting is buttery smooth so maybe its not needed. But I know I have shorted the life of the transmission components at least a little. I did replace the fluid with royal purple back in April, and I am debating on replacing that too one time because of all the rough engaging the transmission has had to deal with in the past few weeks

is there any 3650 rebuild kit? i think my shift fork is gone. second gear doesnt do anythig. cheers

[rio.ohh_]

how much can a shop charge for a job like that??? My 3rd gear grinds all the time and its annoying.

Hey I have a question if you have some time on your hands

[zealvespinhal]

nice. my 2005 mustang wont drive into second gear. you engage the second gear, let the clutch and nothing happens. what could that be?
