1994 Chevy Suburban K1500 4L60e Transmission Problem

I have a 1994 Chevy Suburban K1500 4WD 4L60e Transmission. The problem that I have is, No 2nd gear, 4th gear(overdrive) and reverse gear. Plus I forgot to mention that I got stuck in water that was about 2-3feet deep, and I change the filter and fluid because it was pink. It drove well for about 3 weeks untill I hit a bump in the road and after that I noticed the rpm was getting higher (2000-2500rpm) I slowed and heard a clinking sound in the back, it sounded like a U-joint went out?.... I checked the fluid it was good no burnt smell, the engine coolent was good. I droped the pan and on the bottom of the pan there was a silverish sludge?.. also I can turn the driveshaft a little. So the question is, Do i need a new Transmission or can it be fixed thru the pan . Thanks..

Welcome to Hotrodders.com

A part inside your transmission known as the drive shell has broken. When this breaks there is no 2nd , 4th or reverse gears as you mention.

This is a very common failure in this series of trans. It requires trans removal and disassembly .

Depending on the mileage on the trans, a proper rebuild may be wise at this time
Dont worry how old you are... it is the mileage on your body that adds up.

Thanks for the information on my transmission problem, I don't know about transmissions but i do know about engines, I guess its about time I try it out ... I know I'm going to have fun dropping the transmission, taking it apart, finding out how to take it apart, and putting it all back together. I think im just going to take to a shop. Also what was the silverish sludge that was on the bottom of the pan? was that evidence of the drive shell. Thanks for the info.
