2096 Toyota Camry with P0732 Code: Gear 1 Ratio Issue After Transmission Rebuild and Shift Kit Installation
Hi everyone! I recently rebuilt my 1996 Toyota Camry transmission (A604/41TE) and have less than 1,000 km on it. The rebuild included the A604/41TE Shift Kit by TransGo, which is also compatible with A606 and 42RLE transmissions (more info here: http://www.transmissionpartssales.com/a...42rle.aspx). After installation, I started experiencing a strange issue when starting the car. When I shift into Drive (D), the transmission doesn't respond — it feels like it's in neutral. The vehicle won’t move forward or reverse. Occasionally, after pressing the gas pedal, the transmission responds normally and operates correctly. However, once I stop and try to restart driving, the issue returns. This behavior only occurs when the transmission fluid is cold, and it resolves itself within a few minutes of operation. My mechanic confirmed that this is consistent with the TransGo shift kit’s design — which increases pressure in the piston accumulator to enable faster shifting between 1st and 2nd gear. I’ve also noticed that the vehicle enters LIMP MODE at times due to this issue, but turning off the car and restarting usually resolves it. The problem is intermittent and not constant. My questions are: - Can a TransGo shift kit like this actually cause transmission shifting problems such as P0732 (Gear 1 incorrect ratio)? - Could faulty sensors be responsible? I understand that sensors were likely not replaced during the rebuild, even though they worked before. - Or could it be related to the transmission oil pump? The original pump was used but in better-than-average condition? I’m especially concerned about fluid levels and temperature-related performance. I’ve read that cold fluid can cause shifting issues due to reduced viscosity — which may explain why the problem appears only when the oil is cold. Thanks for any insights! I don’t speak English very well, so please forgive any confusion in my description.
It's possible you have an electrical issue — speed sensors in the transmission should be replaced during a rebuild. Check if your transmission fluid level is within the recommended range and ensure no sensor wiring or connections are damaged.
