07 Pre runner with no reverse

I am currently working on an 07 Toyota Prerunner with no reverse, it also wont rev in park and moves forward in neutral. Has anybody ran across these issues?

 

Tranny sounds fucked

 

Or the shifter linkage is all fucked up

 

Sounds like the linkage. What do you mean by "won't rev in park"?

 

Hey guys and gals I posted a question on a 07 Prerunner with no reverse, acts like it engages but wont spin the wheels, it feels like your are stalling the converter with the brake on giving it some gas. Acts the same way in park. When in neutral it will actually spin the wheels in forward gear.
Thank you for your educated ideas,

 

It acts like you are power braking it, stalling the converter

 

Back ground information needed. What happened before this started.

 

I'm working on this for a friend. They ran the transmission low on fluid due to too short of a drive shaft that was made for it. The cell light was on since the kid owned it. The codes stored in the computer were p0894, p0771, p0776 and p2714.
I tested the solenoids and replaced 3. SL1, S2 and SLT. Don't know how long he was driving it like this. Fluid was fine once topped off. Nothing in pan to be alarmed about. Thank you for reading and any valuable suggestions

 

Sounds like a interesting time to me

 

Maybe drop gearcrucher a PM. He knows his stuff about transmissions.

 

sub'd to find out what wrong with that poor tranny
