Thank you sir for the insight, unfortunately I stay in Owerri. I would have loved to come to your workshop.[

Good evening sir,

Thank you for your description. A gear selector making noise after a 13-pin to 10-pin transmission conversion is a classic example of why full transmission swaps with mismatched pin setups are risky. Such conversions are not plug-and-play — using a 10-pin transmission in place of a 13-pin unit (or vice versa) introduces:

• ECU communication mismatch with the transmission
• Incorrect solenoid control, causing harsh, delayed, or clunky shifts
• Early wear of selector bushings, detents, and cables
• Increased mechanical stress inside the transmission
• Higher risk of transmission going into fail-safe (limp) mode

In Lagos, many mechanics perform these conversions thinking it’s an easy fix, but what actually happens is:

• Cars start showing abnormal noises on gear selection
• Shift engagement feels rough or delayed
• Transmission lifespan reduces due to misaligned electronics and mechanical stress

🔧 Technical Insight

1️⃣ Primary Causes of Gear Selector Noise After Transmission Conversion

• ECU / pin mismatch: Wrong transmission signals make solenoids actuate improperly, producing clunks or metallic noises.
• Linkage / lever stress: Gear lever and cables are now operating outside their designed geometry, causing stiffness or clicks.
• Selector bushings / detents wear: Abnormal stress from mismatched transmission leads to accelerated wear.
• Transmission fluid issues: Old or wrong ATF exacerbates noise, especially when solenoids fire incorrectly.

2️⃣ Symptoms to Expect

• Clicking, clunking, or metallic noise every time lever moves
• Delayed engagement into Drive/Reverse or harsh shifts
• Occasional transmission warning lights or limp mode
• Lever feels loose, stiff, or uneven

3️⃣ Correct Diagnostic & Repair Steps
1. Full scan of ECU and transmission module — identify miscommunication or solenoid errors.
2. Inspect lever bushings, detents, and cables — replace if worn or stressed.
3. Check transmission fluid type, level, and condition — replace if wrong or contaminated.
4. Confirm proper wiring and ECU compatibility — 13-pin transmission needs 13-pin ECU match; reverse conversion if necessary.
5. Test drive and monitor lever movement, noise, and shift quality — do not replace parts randomly.

⚙️ Ryan Automotive Workshop Professional Take

We’ve handled this exact scenario multiple times in Lagos. Many mechanics:

• Perform full transmission pin conversions without correcting ECU or wiring
• Ignore the mechanical and electrical consequences, causing repeat visits
• Replace internal transmission components unnecessarily without proper diagnosis

From our experience:
• 70% of post-conversion gear noise is caused by ECU/transmission mismatch
• 20–30% is due to lever linkage, bushings, or detent stress
• Fluid and solenoid issues make up the rest

Scan-first, inspect-second is the Ryan Automotive approach — it avoids wasted money and further damage.

⸻

🧩 Professional Summary & Next Steps

Short-term:
✅ Avoid forcing the lever — doing so worsens internal stress.
✅ Record a video showing the noise and lever movement for documentation.

If it persists:
➡️ Bring the car for full diagnostic at Ryan Automotive Limited. We will:
• Scan ECU and transmission module
• Inspect linkage, bushings, and solenoids
• Confirm correct transmission-ECU compatibility
• Provide a precise repair or recommendation, including possible reversal of the conversion

Next time you post on Nairaland, include: brand, full model name (e.g., Toyota Camry / Lexus ES350), year, engine size/code, mileage, and recent maintenance history. That allows accurate, professional guidance.

My gear was converted from 13 pins to 10 pins. Few months ago it started making a noise each time I move the gear selector from pack to drive. What could be the problem? And possible solution

Happy weekend my people

Oga iyke, I need engine block for sienna 2005 model. How much will it cost me?

[quote author=Mrkumareze post=111445907]I repaired mine over 2 years, it's still working . It didn't cost me above 90k then.. what is your location [/quote. I dey
Owerri

I had issues with my transmission and I contacted a gear mechanic. He told me that the oil pump of my transmission failed and as a result the fiber got burnt together with the 13pins, and that the only good part remaining is the metal. He gave two options, buying another transmission or repairing the old one.
But I keep hearing that 13pins transmission is not repairable. Please gurus in the house help me, I am a novice when it comes with automatic transmission. I don't want to spend 150k on something that's bound to fail. Thanks

I crashed the gear against a concrete barrier and it got broken. So, the mechanic suggested I should get another empty casing to replace the damaged one.

I needan empty gearbox/case for their toyota sienna 2005 model 13pins.
