Great service! Saved me from ordering the wrong part.
Had a tiny cosmetic issue on arrival. Contacted seller and they solved the problem promptly. Great customer service.
Ordered the wrong one before from another seller. This one was the correct match.
Excellent customer service! I wasn’t sure which transmission control module I needed, but the seller helped me confirm the correct part. The module arrived well packaged and worked perfectly after installation.
Quick response when I messaged the seller.
No codes.
Pre-programmed calibration saved diagnostic and programming time. Unit communicates properly with ECU after installation. Good backup stock option for this common BL chassis transmission fault.
Only issue was that the email confirmation took a little longer than expected.
Delivery took a little longer than estimated, but the part itself is working as expected.
Hit the spot exactly.
I worried about fitment before ordering. The seller accurately matched the part after I provided the VIN. It fits perfectly and saves the trouble of return and exchange.
After 3 weeks of daily commuting, the performance stays stable. No warning lights pop up on dashboard anymore.
Fast delivery, got the part before my scheduled repair.
Communication was smooth throughout the whole order.
Tracking barely updated
Customer service patiently confirmed my VIN to make sure this part fits my car.
Great value! Local shop quoted double the price for the same part. Quality feels solid.
Have been running this part for around 3 months now. No rattles, no weird noises while driving. Quality holds up way better than the cheap one i bought b4.
It's nice when someone actually takes the time to check the fitment.
Part number matched my old one, so ordering was pretty painless.
Had my mechanic take a look at it before installing. He said everything looked good, and so far it’s been working great.
Five stars. Would recommend.
So far it's holding up well. I'll update this review if anything changes.
Saved me hundreds compared to the repair shop quote. Installed it myself and it worked perfectly.
Had some trouble with the address at first, but the seller worked with me and sent out another one.
Fits my vehicle exactly. Plug and play, no extra modification needed.
No problems so far.
The old part was causing intermittent problems. After replacing it with this one, the issue hasn’t come back.
I’m not usually someone who leaves reviews, but this purchase deserved one. The entire experience was better than expected and the part has been performing great.
Shipping was on time, and the part was almost identical to the original one.
