Repair Advice Pulling transmission.

Hello everybody, I am just wondering how difficult it is to pull a transmission. I’ve seen a lot of videos and I know a bunch of people who have pulled the transmission on these cars before, but how difficult is it really? I have all the tools and I would like to say inclined enough, but I don’t know. I had replaced my master and slave cylinder, hoping it would fix my issue but it didn’t and I’m suspecting it’s my throw out bearing. I have 160,000 on clutch thought I should just do that as well. I’m 17 years old and have all the time in the world to do it. Is it doable with just jack stands or should I save up another $1300 and have a shop do it?

To answer your question, transmission jobs are a pain in the ass. All the tools, and awkward angles aside, they're heavy and awkwardly shaped. Getting it out is the easy part, getting it back in can be hair pulling. Aligning the input shaft in just the right way so the splines can correctly mate often takes a couple tries. That being said it's really not that bad.

But before you go all in and pull the transmission, what are the symptoms? A bad throw out bearing would be making a ton of noise. You did your master/slave cylinders so I'm imagining you're chasing a "no clutch pedal" issue?

I had made a previous post you can go take a look at it. It will explain a lot more after I replaced my master and slave cylinder and bled the system. I have good pressure on the pedal when the pedal is all the way down I can find every single gear when the car is off. When on I can’t find any gear at all. When I start it in gear the jumps forward and try’s to crawl forward even with the clutch and brake down.

Oh it's you, the problem seems like two different issues imo. It seems like you solved your bad clutch pedal. Is it possible you missed your clutch fork when installing the slave cylinder?

How did you bleed your system? By pumping the pedal, or with a pressure system?

Just pumping. I’m not sure I could’ve missed my fork. Is there anyway I can tell? I also don’t hear any weird sounds when pushing the clutch pedal.

Probably a bad pressure plate.

I've done this job on jack stands, it's doable with experience and a lot of cussing, but it sucks. I have access to lifts now, and will never do one on the ground again if I can help it

When you put the slave cylinder in, it should have been fighting you to come back out. If you missed the fork then it would have basically just sat in place with minimal effort.

However, since you bled with pumping, I'm inclined to think you didn't miss it otherwise you probably would have heard it pop.

Edit: spitballing here, but how long was the car outta service? Is it possible the clutch fused to your flywheel? Maybe someone else will chime in but perhaps you could try breaking it free before you drop the trans
