700R4 transmission: Why is my 700R4 completely frozen?

Thu, 27 Mar 2025 12:55:58 -0700

After sitting for a month or so, my 700R4 transmission is completely locked up. I start the engine, but when I put it in gear, it slams into gear violently and the engine dies regardless of the RPM. I jacked the rear wheels off the ground and it does the same thing without the wheels even slightly turning. I can rotate the wheels quite easily by hand while on jack stands.

Any thoughts on this greatly appreciated.

Brakes: Whole wheel fell out.

As You can see on the image, whole wheel fell out. I don't know anything about repairing cars and I can't afford mechanic right now, all I know it's a bearing failure. If anyone knows how to fix it step by step or is willing to send me a video of someone repairing it I would be thankful 🫶🏼.

need to know correct connect _{,, when i got the truck the thick red wire and medium sized red wire appeared to have been mended together and broke}, therefore leaving me not knowing what went where.

Engine: Pull cord wonyu pull ôt retract

Fri, 06 Aug 2021 15:44:00 -0700

I habé a huasheng 49cc 4 stroke (engine model 142f) and im pretty sure the oil isi full, the pull cord wouldnt pull but 4 inches. I took the flywheel off and it functions fine, the flywheel rotor rotates about half a turn either way and locks up, after rtying to re-align the rotor and flywheel, also discovered it does not retract unless the disconnected. It sat 3 or 4 days in heavy rain. I needed to chamge a sparkplug, i overtighened the ol sparkplug and it fell apart, i got the last peice from behind the flywheel roter but had no effect. I already tried to turn it when the sparkplug was out to loose compression. Does has anyone had this probem that could help?

Auto Part: Is SBC exhaust bolt pattern symmetrical?

Wed, 20 May 2020 17:34:51 -0700

I'm currently doing a custom build, but space is very limited for the exhaust. I know SBC headers can be flipped by switching driver/passenger sides, but can they be reversed on the same side? Example: can shorty headers be flipped on the same side of the engine for a forward dump? Thanks

700R4 transmission: 93 Firebird auto 1-2 slipping, high revs.

Sat, 20 Oct 2018 09:19:25 -0700

Hi I have a 1993 Firebird Trans am. My transmission started slipping Going into 2nd. It can barely get to 2 but after it shifts into 2nd gear every other gear shifts fine and the rpms are stable. Reverse is fine and neutral, 1st manual, 2nd manual, and 3rd manual. When trying to get into second gear, I get 3-4 thousand rpms and then it may or my not shift into 2nd gear. Sometimes if it gets up to those highly of rpms it won’t let me accelerate until I get into first again and the rpms drop to 1000. Before this happened it shifted to second at 2300 rpms. Started about 3 weeks ago and happened just all of a sudden. Changed my trans fluid, the gasket, on it, put correct amount of fluid in/ type, changed all of the fluids except power steering about 3 months ago. I adjusted the tv cable to where it wants to be, thinking it might not be correct, no result. 73k miles on the trans, 4 speed, not driven hard ever, and haven’t driven it in 3 weeks since then, thinking it may be the governer sticking or going bad- if so need instructions on how to do so. Tried putting Lucas trans fix in, no result. Any thoughts? Need detailed instructions. Has a 4l60 transmission. Didn’t see a thread on a 4l60 trans so I posted it here since they are related closely except having almost no computers in it. Thankyou!

I have a 1983 c10 with the 6.2 Diesel engine. Got in it one day and started out the drive and herd a clank/pop and lost all power and coasted to a stop. Motor running fine, but transmission just won't go. Not making any grinding, whining, or popping noises. Any ideas of what may be wrong?
