97 4t60 sos
So I'm driving and a feel an ever so slight kick. I go to leave a light and my trans does not shift. I mean I can if I keep it into first till 40 then shift. When it'* in other gears it slips and shutters like it wants to grab the next gear. What can this be.
Thanks so much for your help

if you race the engine in second, does it bang in gear ?
if after you drive to like 3000 rpm in 1st, can you shift all the way to D4 and it drives fine but it will not down shift past 3 .... if the computer requests gear 2 from gear 3 you have to downshift to 2 to get back in gear....
been there done that :( big pain.

here is the info from the ATSG TSI
ROLLER CLUTCH FAILURE
COMPLAINT: NO. I: Some 1991-1995 model vehicles equipped with the THM 4T60-E transaxle may
exhibit a no movement condition, with the selector lever in the D4 or 03 ranges, but will
CAUSE:
move when the selector lever is placed into D2 or Lo range.
NO.2: When the engine RPM is increased with the selector lever in the Park or Neutral
position, you may hear a noise that sounds like "Marbles in a Can'', but still moves and shifts
properly.
CORRECTION: The cause for both complaints listed above is a 1-2 roller clutch failure.
Replace the l-2 Roller Clutch Assembly and any related parts that may be damaged or I
broken (See Figure 1). Before installing into the transaxle, always replace the OEM 1-2 roller
clutch springs with Sonnax part number K84956~SP, which contains 16 stronger according
springs and is available from your aftermarket parts supplier (See Figure l).
This is recommended as part of every rebuild to increase transaxle durability.
DO NOT EXCEED 3000 RPM WITH THE SELECTOR LEVER IN REVERSE AND
THE WHEELS OFF THE GROUND. IF YOU DO THIS WITH OEM 1-2 ROLLER
CLUTCH SPRINGS, YOU CAN FAIL THE 1-2 ROLLER CLUTCH BEFORE IT EVER
