C-6 labours reverse and starting

[aussiebko]

Lately my c-6 Which (hasn't done that many miles) is really struggling when first starting and any time I'm in reverse. It's not like its revving the engine really hard, I can put my foot flat to the boards and in reverse it feels like I'm trying to start in 3rd on a hill. Any ideas?
The torque converter was not changed when the transmission went in but I have a new one sitting in the garage. Fluid level is fine also.

Cheers,

Stu

Would improper tension on the band cause this?

Has it been adjusted recently? How long ago was the trans put in and did this issue exist then?

Had a service maybe 2000mi ago. I'm assuming the band Was torqued up then but was under the impression it doesn't affect 1st or reverse. The transmission has done maybe 10-12k miles and the problem did not exist then. I don't think it is band slippage (guessing) as the revs don't go sky high compared to the amount I drive I get. It's more of a really laboured sluggish drive.

The band is for 3rd gear to engage. It tightens the drum to keep it from spinning to lower the gear ratio. If the band was applied during 1st gear, it acts as a brake. I know this from having one too tight after a rebuild once.

It could be that the trans is starting in 3rd gear, which could be the governer is stuck. This is located on the output shaft.

Will a stuck governor cause the sluggish reverse?

No a stuck governer should not cause that. I would check the intermediate beamed adjustment just to be safe. If to tight could drag and cause issues. How are the other shifts?

All the shifts are fine. I decided to install a Hurst V-matic that I bought a while back. The column shift always felt sloppy and I was thinking its possible that the gears were not properly selected which caused some slipping on inclines. Im clutching at straws here but it costs nothing.
A few hours ago selected reverse with the linkage cable disconnected and it didn't appear sluggish backing down my drive. I'll see if the new shifter makes any difference at all I guess.
I've also read that vac signal dictates the clutch application pressure. Not sure if this is true but if it is maybe I should be checking the modulator and also looking for vacuum leaks.
