Transmission problem
Hello everyone,
I just bought my first SVX. Bought her knowing that the transmission is bad. I would like some input. She slips a little when putting her into either reverse or forward. Have to give her a little gas for it to catch. Once she starts going she feels ok. However, I noticed she doesn't want to shift into 3rd gear. She shifts fine from 1st to 2nd.. Any input would be great. I don't know much about the mechanicals of the SVX. However, they sure are BEAUTIES. Only 70,815 miles on her. HELP!! Carlos Proud owner "92" Pearle White |

Think it's time for a rebuild or a replacement. Maybe a brake band adjustment. At least it doesn't shift into 3rd and then not move

Would it be a brake band adjustment if i can drive the car when i put it into first gear on the selector but if i put it into 2,3, or D it will not grip at all, just flares. i get no engine braking at all unless its in 1 also. any help is appreciated, a quick response is also greatly appreciated as i dont know when the next time ill be able to check this is.

Can't think of any thing else, that would cause this. I reckon the box will have to come out. Harvey.

Autos use a freewheel in the rear of the trans so that the gear box can drive the tail shaft but the tail shaft can't drive the gearbox. It is used to allow the change of rotational speed to occur, without the drive line jarring. When the band is applied to stop the front sun gear for 2nd, the ratio suddenly changes, the freewheel unlocks the drive line to prevent the tail shaft from driving the gearbox, thus preventing the shock. This freewheel also prevents engine braking, on over run, it will also prevent reverse gear from driving the Tail shaft, as it turns the output shaft backwards. To allow reverse to work, we have the Low/Reverse clutch, which locks the freewheel to allow reverse and engine braking. The power flow is different in 1st gear, in the D position, than it is in the 1st gear selected position. As the car will drive in 1st position but not in the D position, we can look at this area to see that is used it the 1st, but not in D. Looking at the dia. you can see the freewheels are locked in the D position, but are not locked in the 1st position, as the Low/reverse clutch is applied. This points to the freewheel Sprage clutch not locking up in the D position. Which Sprage is slipping is a guess. If it is the 1/2 then the car may engage 4th gear if it is run fast enough in 1st position, then the selector is put into D. If it is the 3/4 sprage it won't. But as the box has to come out to fix either, it does not matter. Harvey.

I guess it's my turn.
Out of nowhere I lost reverse today. First it slipped badly but moved, second time nothing but slipping. Forward gears seem fine, a hesitation into first but the others shift crisply. I'll start with dropping the pan tomorrow and check out the screen per Harvey's suggestion. It has 74L miles, no abuse.
